Before WILLIAM PRYOR, Chief Judge, JILL PRYOR, and ANDERSON, Circuit
Judges.

PER CURIAM:

      Alfred Rhiner, a Florida prisoner proceeding pro se, appeals the district

court’s entry of judgment in favor of the defendants, based on the district court’s

partial grant of the defendants’ motion to dismiss and subsequent grant of the

defendants’ motion for summary judgment, in his 42 U.S.C. § 1983 action

asserting an Eighth Amendment claim based on the defendants’ failure to protect

him from an assault. On appeal, Rhiner generally contends that the district court

improperly granted the defendants’ motion to dismiss in part by dismissing as a

defendant the Secretary of the Florida Department of Corrections (“FDC”) who

was appointed after his assault, and his claims for injunctive relief. Rhiner

additionally challenges the district court’s denial of his motion to amend his

complaint to add the Secretary of the FDC at the time of his assault, which the

district court had also addressed in its order on the defendants’ motion to dismiss.

Second, Rhiner argues that the district court erred in granting the defendants’

motion for summary judgment on his claims alleging that: (1) he was assaulted by

gang members because of his non-gang member status; (2) he was assaulted with a

razor; and (3) he was assaulted in a known “blind spot,” where prison officials

could not see and assaults regularly occurred. Lastly, Rhiner attempts to challenge

various non-dispositive orders issued by the magistrate judge, including discovery

                                          2
                Case: 18-14037    Date Filed: 06/04/2020    Page: 3 of 20



orders and an order denying his motion to appoint counsel, and argues that there

were still outstanding discovery issues when summary judgment was granted.

    I.       RHINER’S CLAIMS WITH RESPECT TO THE SECRETARIES OF
                  FDC AND HIS CLAIM FOR INJUNCTIVE RELIEF

         “[T]he law is by now well settled in this Circuit that a legal claim or

argument that has not been briefed before the court is deemed abandoned and its

merits will not be addressed.” Access Now, Inc. v. Sw. Airlines Co., 385 F.3d

1324, 1330 (11th Cir. 2004). Furthermore, an issue is considered abandoned

when a party seeking to raise a claim or issue on appeal fails to plainly and

prominently so indicate. See Sapuppo v. Allstate Floridian Ins. Co., 739 F.3d

678, 681-83 (11th Cir. 2014) (explaining that an appellant also abandons a claim

when: (a) he makes only passing references to it, (b) he raises it in a perfunctory

manner without supporting arguments and authority, or (c) the references to the

issue are mere background to the appellant’s main arguments or are buried within

those arguments). Although we liberally construe briefs filed by pro se litigants,

they can abandon issues on appeal by failing to properly brief them. See Timson

v. Sampson, 518 F.3d 870, 874 (11th Cir. 2008) (noting that a pro se litigant

abandoned issues by failing to brief them on appeal).

         We generally review the denial of a motion to amend a complaint for an

abuse of discretion, but review questions of law de novo. Williams v. Bd. of

Regents of Univ. Sys. of Ga., 477 F.3d 1282, 1291 (11th Cir. 2007). After the time
                                            3
              Case: 18-14037     Date Filed: 06/04/2020    Page: 4 of 20



has expired in which a party could have amended as a matter of course, “a party

may amend its pleading only with the opposing party’s written consent or the

court’s leave. The court should freely give leave when justice so requires.”

Fed. R. Civ. P. 15(a)(1)-(2). We have held that “a district court may properly deny

leave to amend the complaint under Rule 15(a) when such amendment would be

futile.” Hall v. United Ins. Co. of Am., 367 F.3d 1255, 1262-63 (11th Cir. 2004).

We have also previously held that, although mere passage of time is an insufficient

reason to deny leave to amend, undue delay could support such a denial. See

Hester v. Int’l Union of Operating Eng’rs, AFL-CIO, 941 F.2d 1574, 1578-79

(11th Cir. 1991) (holding that a party could not amend its complaint after engaging

in undue delay because the party had waited an inexplicably long time after

learning of reason to amend before seeking leave to amend and opportunities to

amend had passed).

      Here, Rhiner has abandoned on appeal the issues of why the district court

improperly dismissed as a defendant the Secretary of the FDC appointed after his

assault, as well as his claims for injunctive relief, by offering only conclusory

statements that the district court erred without addressing the specific reasons the

court gave for those rulings. Furthermore, the district court did not abuse its

discretion in denying Rhiner leave to amend his complaint, because his attempt to

add as a party the Secretary of the FDC at the time of his assault would have been


                                           4
                 Case: 18-14037   Date Filed: 06/04/2020     Page: 5 of 20



futile due to the district court’s dismissal of his injunctive-relief claims.

Accordingly, we affirm as to this issue.

    II.      RHINER’S CHALLENGE TO THE DISTRICT COURT’S GRANT OF
             SUMMARY JUDGMENT WITH RESPECT TO HIS CLAIMS FOR (1)
               GANG MEMBER ASSAULTS ON NON-GANG MEMBERS; (2)
             ASSAULTS WITH RAZORS; AND (3) ASSAULTS IN THE “BLIND
                                    SPOT”

          We review a district court’s grant of summary judgment de novo, applying

the same legal standards used by the district court. Brown v. Crawford, 906 F.2d

667, 669 (11th Cir. 1990). The question is whether the evidence, when viewed in

the light most favorable to the nonmoving party, shows that no genuine issue of

material fact exists, and that the moving party is entitled to judgment as a matter of

law. Id. “An issue of fact is ‘material’ if, under the applicable substantive law, it

might affect the outcome of the case. An issue of fact is ‘genuine’ if the record

taken as a whole could lead a rational trier of fact to find for the nonmoving party.”

Harrison v. Culliver, 746 F.3d 1288, 1298 (11th Cir. 2014) (discussing the

summary judgment standard in Fed. R. Civ. P. 56(a)). We generally will not

consider the merits of issues not raised before the district court. Narey v. Dean, 32

F.3d 1521, 1526-27 (11th Cir. 1994). Likewise, the record on appeal consists

solely of the original papers and exhibits filed in the district court, the transcript of

any proceedings, and a certified copy of the docket entries prepared by the district

clerk. Fed. R. App. P. 10(a).


                                            5
              Case: 18-14037     Date Filed: 06/04/2020    Page: 6 of 20



      Unsupported factual allegations, affidavits based on information and belief

instead of personal knowledge, and mere conclusions are insufficient to withstand

a motion for summary judgment. Ellis v. England, 432 F.3d 1321, 1327 (11th

Cir. 2005). We have held that a plaintiff’s sworn statement containing

“descriptions of specific, discrete facts of the who, what, when, and where variety”

was not conclusory and could be considered at the summary judgment stage.

Feliciano v. City of Miami Beach, 707 F.3d 1244, 1253 (11th Cir. 2013). Evidence

that would be inadmissible at trial cannot defeat summary judgment. Corwin v.

Walt Disney Co., 475 F.3d 1239, 1249 (11th Cir. 2007); see also Jones v. UPS

Ground Freight, 683 F.3d 1283, 1293-94 (11th Cir. 2012) (noting that a district

court can consider hearsay in support of summary judgment if that hearsay

statement can be “reduced to admissible form”). Furthermore, “[w]hen opposing

parties tell two different stories, one of which is blatantly contradicted by the

record, so that no reasonable jury could believe it, a court should not adopt that

version of the facts for purposes of ruling on a motion for summary judgment.”

Scott v. Harris, 550 U.S. 372, 380 (2007).

      Section 1983 of Title 42 of the U.S. Code creates a private right of action

against any person acting under the color of state law who deprives another of any

constitutional right. 42 U.S.C. § 1983. For prisoners, “[t]he Eighth Amendment

can give rise to claims challenging specific conditions of confinement, the


                                           6
              Case: 18-14037     Date Filed: 06/04/2020   Page: 7 of 20



excessive use of force, and the deliberate indifference to a prisoner’s serious

medical needs.” Thomas v. Bryant, 614 F.3d 1288, 1303-04 (11th Cir. 2010).

Beyond restraining prison officials from inflicting “cruel and unusual

punishments” upon inmates, the Eighth Amendment requires officials to take

reasonable measures to guarantee the safety of the inmates, including protecting

inmates from violence at the hands of other inmates. Bowen v. Warden, Baldwin

State Prison, 826 F.3d 1312, 1319-20 (11th Cir. 2016). To survive summary

judgment on a plaintiff’s failure-to-protect claim, the plaintiff must produce

sufficient evidence showing the existence of (1) a substantial risk of serious harm;

(2) the defendants’ deliberate indifference to that risk; and (3) causation. Caldwell

v. Warden, FCI Talladega, 748 F.3d 1090, 1099 (11th Cir. 2014).

      The first element of a failure-to-protect claim—whether a substantial risk of

serious harm existed—is an objective determination. Purcell ex rel. Estate of

Morgan v. Toombs Cty., Ga., 400 F.3d 1313, 1321 (11th Cir. 2005). To show a

substantial risk of serious harm, a prisoner must provide evidence that there was a

“strong likelihood” of his injury occurring, because the mere possibility of injury is

not enough. Brooks v. Warden, 800 F.3d 1295, 1301 (11th Cir. 2015) (citation

omitted). The occurrence of the prisoner’s injury is also not enough, on its own, to

show after the fact a substantial risk of serious harm. Id. at 1302. We have held

that, where a “perfect storm of events” was necessary for the plaintiff’s injury to


                                          7
              Case: 18-14037     Date Filed: 06/04/2020     Page: 8 of 20



occur, there was not a substantial risk of serious harm. Id. at 1303 (quotation

marks omitted).

      In Purcell, we stated that, while confinement in a prison where “violence

and terror reign is actionable,” an occasional, isolated attack by one prisoner on

another may not constitute cruel and unusual punishment. Purcell, 400 F.3d at

1320. We then held that, viewing the facts of the case in the light most favorable

to a jail inmate, no substantial risk of serious harm existed because there was no

history of violence that showed that prisoners were exposed to a “constant threat of

violence.” Id. at 1321-22 & n.21 (noting that (1) although inmate fighting did

occur, it was not the norm, and it was not linked to any recurring specific cause,

and (2) in a jail that housed over a hundred inmates, evidence of only two or three

serious fights over a nine-month period did not establish that serious

inmate-on-inmate violence was frequent or pervasive). Furthermore, we have held

that 33 incidents involving weapons, out of a prison population between 830 and

990 inmates, where only 4 incidents occurred in the “back hallway” in which the

plaintiff was assaulted, was “hardly sufficient to demonstrate” that violence and

terror reigned at the prison. Harrison, 746 F.3d at 1300.

      The second element of a failure-to-protect claim—deliberate indifference to

a substantial risk of harm—has three components: (1) subjective knowledge of a

risk of serious harm; (2) disregard of that risk; and (3) conduct that is more than


                                          8
              Case: 18-14037      Date Filed: 06/04/2020    Page: 9 of 20



gross negligence. Id. at 1298. To show disregard of risk, the plaintiff must

produce evidence that the defendant disregarded a risk by failing to respond to it in

an objectively reasonable manner. Caldwell, 748 F.3d at 1099. Prison officials

might avoid Eighth Amendment liability where they show: (1) “that they did not

know of the underlying facts indicating a sufficiently substantial danger and that

they were therefore unaware of a danger”; (2) “that they knew the underlying facts,

but believed . . . that the risk to which the facts gave rise was insubstantial or

nonexistent”; or (3) “that they responded reasonably to the risk, even if the harm

ultimately was not averted.” Rodriguez v. Sec’y for Dep’t of Corr., 508 F.3d 611,

617-18 (11th Cir. 2007) (quotation marks omitted) (quoting Farmer v. Brennan,

511 U.S. 825, 844 (1994)).

      Finally, to impose supervisory liability, a prisoner must show either that the

prison official directly participated in the unconstitutional conduct or that there was

a “causal connection” between the prison official’s conduct and the constitutional

violation. Harrison, 746 F.3d at 1298. To show this causal connection, the

prisoner must show that there was “a history of widespread abuse” that put the

supervising official “on notice of the need to correct the alleged deprivation,” yet

the official failed to do so. Id. (citation omitted). Alternatively, a causal

connection can be shown if a supervisor had a “custom or policy” that resulted in

deliberate indifference to a prisoner’s constitutional rights. Id. (citation omitted).

Furthermore, lay witnesses may not offer testimony on scientific matters that fall

under the scope of expert-witness testimony. Fed. R. Evid. 701 & 702.

      Here, the district court did not err in granting summary judgment for the

defendants on Rhiner’s gang-violence, razor-assault, and blind-spot claims because

he failed to provide sufficient evidence creating a genuine issue of material fact as

to whether there was a substantial risk of serious harm, the defendants had

subjective knowledge of any risk, or the defendants’ deliberate indifference caused

a constitutional violation.

      A. Gang Member Assaults on Non-Gang Members

      First, as to Rhiner’s claim regarding gang member on non-gang member

violence, he failed to provide sufficient evidence to create a genuine dispute of

material fact as to whether pervasive violence existed that presented a substantial

risk of serious harm, whether the defendants had subjective knowledge of that risk,

or whether there was causation between some deliberate indifference and his

injuries. While Rhiner contends that he submitted enough evidence to show that

gang member on non-gang member assaults constituted a substantial risk of serious

harm, the only evidence in the record tending to show that there were a large

number of gang member on non-gang member assaults consisted of Rhiner’s and

other inmates’ conjectures on the number of assaults. Even if those affidavits were

proper, which they may not have been due to Rhiner’s express promise to give the


                                          10
             Case: 18-14037     Date Filed: 06/04/2020   Page: 11 of 20



inmates a portion of his potential damages award, the inmates’ statements were

insufficient to meet the summary judgment burden because they lacked any

specifics and consisted of unsupported factual allegations and statements based on

belief instead of personal knowledge. See Ellis, 432 F.3d at 1327. Furthermore,

unlike the sworn and detailed statements in Feliciano that provided who, what,

when, and where information, the inmates’ statements here offered no information

on how they came to learn the information or on what they based their numerical

estimates. See Feliciano, 707 F.3d at 1253. Rhiner additionally conceded that,

when he said that gang assaults were well documented, he was referring to

documentation within OCI’s database. Thus, the only true evidence for summary

judgment purposes as to the pervasive nature of gang violence at OCI consisted of

Johnson’s affidavit discussing ten possible gang-related assaults in the

approximately two years preceding Rhiner’s assault, which, by itself, is too

infrequent under this Court’s precedent to establish that gang on non-gang assaults

constituted a substantial risk of serious harm. See, e.g., Harrison, 746 F.3d at

1300; Purcell, 400 F.3d at 1321-22 & n.21.

      Similarly, Rhiner failed to show a genuine issue of material fact as to

whether the defendants were deliberately indifferent by failing to produce

sufficient evidence that they had subjective knowledge of a substantial risk of

serious harm. Even if Rhiner’s evidence had shown that there were more than ten


                                         11
             Case: 18-14037     Date Filed: 06/04/2020    Page: 12 of 20



gang-related assaults, he failed to show that the defendants subjectively knew of

those other assaults. Severson and Snyder both stated in their affidavits that they

got their information on assaults from OCI’s database, , and, according to Johnson,

OCI’s database showed at most only ten gang member on non-gang member

assaults in the two years preceding Rhiner’s assault. Furthermore, inmate Otero

testified that inmates rarely told officers about fights, and inmate Handley stated in

his affidavit that inmates rarely told officers the truth about assaults and made up

stories to explain their injuries. Thus, Rhiner failed to show that the defendants

had subjective knowledge of a substantial risk of serious harm. See Rodriguez, 508

F.3d at 617-18.

      Furthermore, Rhiner failed to show that there was a causal connection

between the defendants’ conduct and any Eighth Amendment violation. See

Harrison, 746 F.3d at 1298. Rhiner failed to show a history of widespread gang-

related violence against non-gang members sufficient to put prison officials on

notice of the need to correct the alleged deprivation, because the record suggests

there were only ten such assaults at most in the relevant two-year period. Further,

Rhiner failed to show that a policy or practice of the defendants caused his injury,

as Rhiner’s own deposition suggested that the likely reason for the assault was the

result of a personal disagreement between himself and another inmate, rather than




                                          12
             Case: 18-14037     Date Filed: 06/04/2020    Page: 13 of 20



a simple rumor that the assault stemmed from gang members being housed with

non-gang members. See Harrison, 746 F.3d at 1298.



      B. Assaults with Razors

      As to Rhiner’s razor-assault claim, he similarly failed to provide sufficient

evidence showing a genuine dispute of material fact as to whether there was a

substantial risk of harm regarding razors, whether the defendants had subjective

knowledge of the risk that razors presented, and whether his injuries were caused

by the defendants’ deliberate indifference. First, Rhiner failed to demonstrate that

razors constituted a substantial risk of harm or that the defendants had subjective

knowledge of that risk. The only evidence that Rhiner submitted indicating that

razor assaults could potentially constitute a substantial risk of serious harm

consisted of inmate conjectures of the number of razor assaults. Those affidavits

had the same problems as previously discussed above, in that, even if they were

proper notwithstanding Rhiner’s promise of future compensation, those documents

lacked specific details on how those individuals came to those numbers, and

otherwise contained only unsupported factual assertions that were insufficient to

create a genuine issue of material fact for summary judgment purposes. See

Feliciano, 707 F.3d at 1253; Ellis, 432 F.3d at 1327. Furthermore, OCI’s database

information, as well as sworn affidavits from Sergeant McGee-Aviano and Snyder,


                                          13
             Case: 18-14037     Date Filed: 06/04/2020   Page: 14 of 20



indicated that there were only seven assaults involving razors and that they had no

subjective knowledge of a large number of razor assaults. Additionally, inmate

Handley stated in his subsequent affidavit that inmates often made up stories

regarding the cause of their injuries, such that the defendants may not have been

able to know of a large number of razor assaults, even if the actual number was

higher than perceived. Overall, the evidence that was provided showed that there

was no substantial risk of serious harm and that the defendants had no subjective

knowledge of any potential risk, especially in light of Rhiner’s statement that he

was using OCI’s database as the basis for his contention that the razor assaults

were well-documented.

      Rhiner also failed to provide sufficient evidence creating a genuine issue of

material fact as to causation. Rhiner failed to connect any action, policy, or

practice of Severson or Snyder to assaults using razors. See Harrison, 746 F.3d at

1298. While Rhiner initially alleged in his complaint that the prison’s razor-

exchange policy caused an increase in razor-based violence, the inmate statements

that he submitted in opposition to the defendants’ motion for summary judgment

did not address the defendants’ implementation of the razor-exchange policy, and

the article on public-interest groups seeking to enjoin Alabama prisons from

allowing prisoners unlimited access to razors had no factual bearing on OCI’s

razor-exchange policy. By contrast, the defendants proffered Deputy Hiss’s


                                         14
              Case: 18-14037     Date Filed: 06/04/2020    Page: 15 of 20



affidavit detailing OCI’s policies and practices to ensure that the razors handed out

in the exchange were returned.

      Additionally, even if Rhiner’s razor-assault claim is based on a theory other

than supervisory liability, Rhiner failed to show that his wounds actually were

caused by a razor because: (1) he was unconscious during the assault and could not

have seen the weapon that his assailants used to cut him, and (2) although inmates

Handley and Reid initially stated in their “written depositions” that they saw the

assailants cut him with a razor, they later clarified their statements in their sworn

affidavits and stated that they did not know for sure that the assailants had used a

razor and had only assumed so. Although Rhiner stated that he personally believed

his cuts were caused by a razor, based on his 21 years of seeing razor cuts, that

testimony would have been inadmissible at trial because it was improper lay-

witness testimony regarding the medical cause of his cuts, which prevented it from

being used to defeat summary judgment. See Fed. R. Evid. 701 & 702; Corwin,

475 F.3d at 1249. Rather, the only admissible evidence on the cause of Rhiner’s

cuts came from Bass, a registered nurse, who stated that Rhiner’s wounds were too

jagged to have come from a razor, and that Bass believed they were more likely

caused by a piece of metal that had been sharpened to an edge. Last, although

Rhiner states that he has unspecified newly obtained medical evidence that his

wounds were caused by a razor, that evidence was not part of the record before the


                                          15
             Case: 18-14037     Date Filed: 06/04/2020    Page: 16 of 20



district court and cannot be considered for the first time on appeal. See Fed. R.

App. P. 10(a). Thus, Rhiner failed to establish the requisite causation necessary to

support his deliberate-indifference claims regarding razor violence.

      C. Assaults in the Blind Spot

      Third, Rhiner’s blind-spot claim fails because he failed to provide sufficient

evidence to create a genuine issue of material fact as to whether the lack of security

in the blind spot constituted a substantial risk of serious harm or whether the

defendants had subjective knowledge of that risk. The evidence that Rhiner

submitted tending to show that the blind spot constituted a substantial risk of

serious harm consisted of: (1) inmate Handley’s statement in his “written

deposition” that Rhiner was assaulted near the chow hall’s north entrance because

it was a blind spot that officers could not see; (2) inmate Reid’s statement in his

“written deposition” that Rhiner was assaulted near the north entrance because it

was a blind spot that security did not monitor, and assaults happened at the north

entrance “all the time;” and (3) Otero’s deposition statements that Rhiner was

assaulted at the north entrance, which was a blind spot, and it was not uncommon

for fights to occur in that area. Although those statements tended to support

Rhiner’s allegation that the blind spot was a well-known location for assaults and

presented a substantial risk of serious harm, neither the affiants nor Rhiner himself

provided specific facts to support their anecdotal perceptions, which made those

general statements insufficient to withstand the motion for summary judgment.

See Ellis, 432 F.3d at 1327. Rather, the objective evidence indicated that only

three incidents had occurred near the north entrance in the year prior to Rhiner’s

assault, which is too infrequent under this Court’s precedent to establish that gang

on non-gang assaults constituted a substantial risk of serious harm. See, e.g.,

Harrison, 746 F.3d at 1300; Purcell, 400 F.3d at 1321-22 & n.21.

      Furthermore, Rhiner did not submit sufficient evidence showing that the

defendants had subjective knowledge of any perceived risk posed by the blind spot.

Rather, Severson and Snyder submitted affidavits attesting that they had no such

knowledge, Sergeant McGee-Aviano and Lieutenant Campbell stated that the

officers generally did not recall assaults near the north entrance being common,

and inmate Otero stated at his deposition that inmates rarely notified prison

officials when incidents did occur in the blind spot. Although Snyder stated that he

had occasional discussions about chow hall security generally, nothing about that

broad statement established his awareness of any substantial risk of harm,

especially when he specifically disputed that premise in making his statement that

he had occasional security discussions. See Harrison, 746 F.3d at 1298. Thus,

Rhiner failed to provide evidence creating a genuine dispute of material fact as to

whether the blind spot constituted a substantial risk of serious harm or whether the

defendants had a subjective knowledge of that risk.

      Accordingly, we affirm as to this issue.

    III.   RHINER’S CLAIMS CHALLENING THE MAGISTRATE JUDGE’S
                         NON-DISPOSITIVE ORDERS

      Section 636(b)(1)(A) of Title 28 of the U.S. Code provides that a district

judge may designate a magistrate judge to hear non-dispositive pretrial matters

pending before the district judge, including discovery motions. 28 U.S.C.

§ 636(b)(1)(A). When a magistrate judge rules on a pretrial matter pursuant to

§ 636(b)(1)(A), “[a]ppeals from the magistrate’s ruling must be to the district

court,” and we lack jurisdiction to hear appeals “directly from federal magistrates.”

United States v. Renfro, 620 F.2d 497, 500 (5th Cir. 1980); see also Donovan v.

Sarasota Concrete Co., 693 F.2d 1061, 1066-67 (11th Cir. 1982) (11th Cir. 1982)

(noting that a magistrate judge’s decision must be rendered final by the district

court prior to appeal). More recently, we have applied Renfro in cases where a

magistrate judge issues an order on a non-dispositive issue, a party fails to object to

the order, and the same party subsequently appeals from the final judgment.

United States v. Schultz, 565 F.3d 1353, 1359-62 (11th Cir. 2009); United States v.

Brown, 299 F.3d 1252, 1259-60 (11th Cir. 2002) (stating that we lack jurisdiction

to review a magistrate judge’s order where the defendant fails to “ever raise[] the

issue before the district court for review of the magistrate judge’s order”),

judgment vacated and remanded, 538 U.S. 1010 (2003), opinion reinstated on

remand, 342 F.3d 1245, 1246 (11th Cir. 2003) (refusing to depart from Renfro as
                                          18
              Case: 18-14037    Date Filed: 06/04/2020    Page: 19 of 20



prior panel precedent). In Schultz, we added that this jurisdictional rule applies

even if a magistrate judge fails to provide notice, in the order on non-dispositive

matters, that objections must be filed within the applicable time limits. 565 F.3d

at 1361-62.

      Federal Rule of Civil Procedure 72(a) provides that any objections to a

magistrate judge’s non-dispositive pretrial order are to be made within 14 days,

and that a party “may not assign as error a defect in the order not timely objected

to.” Fed. R. Civ. P. 72(a). Applying Rule 72(a), we have, in several cases,

considered a party’s failure to object to a magistrate judge’s non-dispositive order

as a waiver of the right to raise that issue on appeal from the final judgment,

without considering jurisdiction. See, e.g., Smith v. Sch. Bd. of Orange Cty.,

487 F.3d 1361, 1365-66 (11th Cir. 2007) (holding that a pro se appellant waived

the right to appeal certain discovery orders entered by a magistrate judge because

he did not timely object to them before the district court); Farrow v. West, 320

F.3d 1235, 1248 n.21 (11th Cir. 2003) (“A party failing to appeal a magistrate

judge’s order in a nondispositive matter to the district court may not raise an

objection to it on appeal to a circuit court.”). Although in those cases we did not

apply the jurisdictional rule in Renfro, and we instead relied on waiver principles,

cases that consider a magistrate’s order without explicitly addressing whether we

have jurisdiction to do so are not binding precedent for the proposition that we


                                          19
              Case: 18-14037    Date Filed: 06/04/2020    Page: 20 of 20



have jurisdiction. See generally King v. Cessna Aircraft Co., 505 F.3d 1160, 1168

(11th Cir. 2007) (“[T]he prior precedent rule does not extend to implicit

jurisdictional holdings.”); Okongwu v. Reno, 229 F.3d 1327, 1330 (11th Cir. 2000)

(stating that we are not bound by a prior panel’s sub silentio treatment of a

jurisdictional question).

      Here, we are without jurisdiction to review Rhiner’s challenges to

non-dispositive orders from the magistrate judge because he failed to object to

those orders and appeal them to the district court. Furthermore, the record

contradicts Rhiner’s contention that there were outstanding discovery issues at the

time summary judgment was granted. Accordingly, we affirm as to this issue.

      AFFIRMED.
