PER CURIAM:

          A jury convicted Matthew Dwayne Smith, Ernest Van Carr,

and Angel Gonzalez of conspiracy to distribute more than fifty

grams of crack cocaine, in violation of 21 U.S.C. § 846 (2000), and

various substantive offenses, in violation of 21 U.S.C. § 841(a)(1)

(2000), and 18 U.S.C. § 2 (2000).      In these consolidated appeals,

Appellants challenge their convictions and sentences.         Finding no

reversible error, we affirm.



                                I.   Carr

          On   appeal,   Carr    asserts    that   the     evidence   was

insufficient to convict him of conspiracy to possess with intent to

distribute and to distribute crack cocaine because the Government

failed to prove an interdependence between him, Gonzalez, and Smith

sufficient to show that he knowingly joined the conspiracy.            We

review de novo the district court’s decision to deny a motion for

judgment of acquittal under Fed. R. Crim. P. 29.         United States v.

Smith, 451 F.3d 209, 216 (4th Cir.), cert. denied, 127 S. Ct. 197

(2006).   Where, as here, the motion was based on a claim of

insufficient evidence, “[t]he verdict of a jury must be sustained

if there is substantial evidence, taking the view most favorable to

the Government, to support it.” Glasser v. United States, 315 U.S.

60, 80 (1942); Smith, 451 F.3d at 216.      This court “can reverse a

conviction on insufficiency grounds only when the prosecution’s


                                 - 3 -
failure is clear.”       United States v. Moye, 454 F.3d 390, 394 (4th

Cir.)   (internal   quotation      marks   and   citation     omitted),     cert.

denied, 127 S. Ct. 452 (2006).

           “To   prove    a   conspiracy    under     21   U.S.C.   §    846,   the

government must prove (1) an agreement between two or more persons

to engage in conduct that violates a federal drug law, (2) the

defendant’s knowledge of the conspiracy, and (3) the defendant’s

knowing and voluntary participation in the conspiracy.”                    United

States v. Strickland, 245 F.3d 368, 384-85 (4th Cir. 2001); United

States v. Burgos, 94 F.3d 849, 857 (4th Cir. 1996) (en banc).

A defendant may be convicted of conspiracy without knowing all the

conspiracy’s     details,     as   long    as    he   joins   the       conspiracy

understanding its unlawful nature and willfully joins in the plan

on at least one occasion.           Burgos, 94 F.3d at 858.              Once the

existence of a conspiracy is established, only a slight link

between a defendant and the conspiracy is needed to support a

conviction. United States v. Cardwell, 433 F.3d 378, 390 (4th Cir.

2005), cert. denied, 126 S. Ct. 1669 (2006).                Our review of the

trial testimony convinces us that the Government demonstrated

Carr’s knowing participation in the conspiracy.                 Although Carr

asserts that some of the Government’s witnesses were not credible,

“[w]e do not review the credibility of the witnesses and assume the

jury resolved all contradictions in the testimony in favor of the




                                    - 4 -
government.”          United States v. Sun, 278 F.3d 302, 313 (4th Cir.

2002).

               Next, Carr asserts that the evidence was insufficient to

prove that he aided and abetted Smith’s distribution of crack on

July 20, 2004 (Count 9).              Carr contends that the confidential

informant contacted Smith for crack and that Carr was “simply

present” at the drug deal but did not aid, abet, or assist.                           “A

defendant is guilty of aiding and abetting if he has knowingly

associated himself with and participated in the criminal venture.”

Burgos, 94 F.3d at 873 (internal quotation marks and citation

omitted).        We    conclude     that    the    evidence    presented      at   trial

supported the jury’s guilty verdict on Count 9.                      See id.; see also

United   States        v.   Alerre,   430    F.3d    681,   689      (4th   Cir.   2005)

(discussing elements of offense of distribution of a controlled

substance), cert. denied, 126 S. Ct. 1925 (2006).

               Carr also contends on appeal that the Government failed

to prove that he aided and abetted Smith’s possession of crack

cocaine with the intent to distribute on July 20, 2004 (Count 10).

Carr asserts that, because officers seized the crack from Smith’s

pants pocket, he (Carr) could not have constructively possessed the

crack because he did not have dominion and control over the car

where    the    drugs       were   found.      Although       Carr    challenges    his

constructive possession of the drugs, the issue is whether Carr

aided and abetted Smith’s possession of crack with intent to


                                           - 5 -
distribute.      The evidence at trial disclosed that Smith had actual

possession of 5.2 grams of crack cocaine when he was arrested after

a   controlled     buy   with    a     confidential     informant.      See    United

States v. Collins, 412 F.3d 515, 519 (4th Cir. 2005) (setting forth

elements of offense of possession with the intent to distribute).

By assisting Smith in the actual distribution of crack (the offense

charged in Count 9), it was reasonable for the jury to infer that

Carr knew Smith was involved in the illegal distribution of a

controlled     substance        and     knowingly      participated    in     Smith’s

possession of crack cocaine with the intent to distribute.                        See

Burgos, 94 F.3d at 873. Accordingly, we conclude that the evidence

was sufficient to support the jury’s verdict on Count 10.

             Turning to Carr’s challenges to his 151-month sentence,

he first asserts that the district court erred when it refused to

sentence     him   below    the       advisory    sentencing    guideline      range

calculated using the 100:1 crack-to-powder cocaine ratio.                       Carr

correctly concedes that his argument is foreclosed by our decision

in United States v. Eura, 440 F.3d 625, 633-34 (4th Cir. 2006),

petition for cert. filed, __ U.S.L.W. __ (U.S. June 20, 2006) (No.

05-11659).     Although Carr urges us to reconsider our holding in

Eura,   “a   panel   of    this       court   cannot    overrule,    explicitly    or

implicitly, the precedent set by a prior panel of this court.                   Only

the Supreme Court or this court sitting en banc can do that.”

Scotts Co. v. United Indus. Corp., 315 F.3d 264, 271-72 n.2 (4th


                                         - 6 -
Cir. 2002) (internal quotation marks and citation omitted).                Thus,

Carr is not entitled to relief on this claim.

             Next, Carr asserts that the district court failed to

adequately consider the factors in 18 U.S.C.A. § 3553(a) (West 2000

& Supp. 2006), before sentencing him, that the court effectively

applied a mandatory sentencing guidelines scheme, and that his

sentence is unreasonable because he received the same sentence

Gonzalez received.         After United States v. Booker, 543 U.S. 220

(2005), a district court is no longer bound by the range prescribed

by the sentencing guidelines.         United States v. Hughes, 401 F.3d

540,   546   (4th   Cir.    2005).    However,   in   imposing     a   sentence

post-Booker, courts still must calculate the applicable guideline

range after making the appropriate findings of fact and consider

the range in conjunction with other relevant factors under the

guidelines and § 3553(a). United States v. Moreland, 437 F.3d 424,

432 (4th Cir.), cert. denied, 126 S. Ct. 2054 (2006).              This court

will affirm a post-Booker sentence if it “is within the statutorily

prescribed    range   and    is   reasonable.”    Id.   at   433       (internal

quotation marks and citation omitted).           “[A] sentence within the

proper advisory Guidelines range is presumptively reasonable.”

United States v. Johnson, 445 F.3d 339, 341 (4th Cir. 2006).

             Our review of the record leads us to conclude that the

district court appropriately treated the guidelines as advisory and

sentenced Carr only after considering and examining the sentencing


                                     - 7 -
guidelines and the § 3553(a) factors, as instructed by Booker.

Carr suggests that his sentence is unreasonable because it was the

same as Gonzalez’s, whose participation in the conspiracy Carr

alleges was greater than his.        See 18 U.S.C.A. § 3553(a)(6).           Carr

and Gonzalez, however, do not have similar criminal histories.                  In

addition, Carr’s 151-month sentence is below the statutory maximum

sentence of life imprisonment.             See 21 U.S.C.A. § 841(b)(1)(A)

(West 1999 & Supp. 2006).          Finally, neither Carr nor the record

suggests any information so compelling as to rebut the presumption

that a sentence within the properly calculated guideline range is

reasonable.     We     therefore    conclude      that    the   district   court

adequately considered the § 3553(a) factors before imposing Carr’s

sentence and that the sentence is reasonable.



                              II.    Gonzalez

            Gonzalez    contends    that    the   district      court   erred    in

denying his motion for a mistrial in light of testimony that he

threatened a woman with a gun in an effort to recover stolen drug

proceeds.     Gonzalez    correctly    notes      that,    before   trial,      the

district court excluded that testimony as unfairly prejudicial

under Fed. R. Evid. 403.           This court reviews for an abuse of

discretion a district court’s denial of a motion for a mistrial.

United States v. Stockton, 349 F.3d 755, 762 (4th Cir. 2003).                    We

have held that “[a] defendant must show prejudice in order for the


                                    - 8 -
court’s   ruling   to   constitute    an     abuse   of    discretion,    and   no

prejudice    exists     if   the   jury    could     make    individual    guilt

determinations by following the court’s cautionary instructions.”

United States v. West, 877 F.2d 281, 288 (4th Cir. 1989).

            We find no abuse of discretion in the district court’s

denial of Gonzalez’s motion for a mistrial.               Immediately after the

witness’ testimony about the excluded incident, the district court

directed the jury to disregard the witness’ statement and, in its

final instructions to the jury, also stated that “[a]ny evidence to

which an objection was sustained by the Court, and any evidence

ordered stricken by the Court, must be entirely disregarded.”

(JA-III at 1235).       We presume that the jury followed the court’s

instructions to disregard the testimony about the gun.               See United

States v. Williams, 461 F.3d 441, 451 (4th Cir.), cert. denied, 127

S. Ct. 616 (2006).       Moreover, our review of the trial testimony

convinces us that the jury independently determined Gonzalez’s

guilt on each count against him.           See West, 877 F.2d at 288.

            Gonzalez also asserts that his trial counsel* provided

ineffective assistance by introducing evidence of a prior state

court conviction for possession of cocaine on the same day as the

offense charged in Count 5 of the indictment.                  We “may address

[claims of ineffective assistance of counsel] on direct appeal only

if the lawyer’s ineffectiveness conclusively appears from the

                                     - 9 -
record.”     United States v. Baldovinos, 434 F.3d 233, 239 (4th

Cir.), cert. denied, 126 S. Ct. 1407 (2006); see Strickland v.

Washington, 466 U.S. 668, 687-88, 694 (1984) (discussing standard

for claims of ineffective assistance of counsel).      Applying these

standards, we decline to review this claim on direct appeal.

             Gonzalez next challenges his sentence, asserting that the

district court erred by enhancing his base offense level two levels

for possession of a weapon under U.S. Sentencing Guidelines Manual

§ 2D1.1(b)(1) (2005).     We review the district court’s application

of the enhancement under § 2D1.1(b)(1) for clear error. See United

States v. McAllister, 272 F.3d 228, 234 (4th Cir. 2001).         This

“adjustment should be applied if the weapon was present, unless it

is clearly improbable that the weapon was connected with the

offense.”     USSG § 2D1.1(b)(1), cmt. n.3; see McAllister, 272 F.3d

at 233-34.    Our review of the record convinces us that the district

court did not clearly err in applying the enhancement.



                              III.   Smith

             Smith asserts on appeal that the district court erred in

relying on the testimony of William Tolbert to determine the amount

of drugs attributable to him.         In evaluating Tolbert’s trial

testimony at sentencing, the district court did not wholly reject

it.   Rather, the court used only conservative estimates of the

portions of Tolbert’s testimony the court deemed to be credible.


                                 - 10 -
See Sun, 278 F.3d at 313.      Given this approach, we conclude that

the district court’s credibility determination and its ultimate

determination of drug quantity should not be disturbed on appeal.



                             IV.    Conclusion

            Accordingly, we affirm Smith’s sentence, affirm Carr’s

convictions and sentence, and affirm Gonzalez’s convictions and

sentence.     We   also   decline    to   review   Gonzalez’s   ineffective

assistance of counsel claim on direct appeal.              We dispense with

oral   argument    because   the    facts    and   legal   contentions   are

adequately presented in the material before the court and argument

would not aid the decisional process.



                                                                   AFFIRMED
