          Appeal from the United States District Court
               for the Southern District of Texas
                      USDC No. G-97-CV-605
                      --------------------
                          June 13, 2001

Before WIENER, DeMOSS, and DENNIS, Circuit Judges.

PER CURIAM:*

     Terry R. Petitt, Texas prisoner number 481296, contends that

the district court erred in dismissing his civil rights complaint

as frivolous.    See 28 U.S.C. § 1915A(b)(1).   Petitt contends that

his right to due process was violated during a prison

disciplinary proceeding because he was not provided with

procedural safeguards required by Wolff v. McDonnell, 418 U.S.

539, 563-66 (1974).   Because Petitt's good-time credits have been

restored and the length of his sentence has not been affected,


     *
       Pursuant to 5TH CIR. R. 47.5, the court has determined that
this opinion should not be published and is not precedent except
under the limited circumstances set forth in 5TH CIR. R. 47.5.4.
                           No. 00-40925
                                -2-

Petitt's liberty interests are not implicated by the disciplinary

proceeding.   See Sandin v. Conner, 515 U.S. 472, 484 (1995);

Madison v. Parker, 104 F.3d 765, 767-68 (5th Cir. 1997).       Petitt

does not have a protected liberty interest in his custodial

classification and his 15-day placement in administrative

segregation "does not constitute a deprivation of a

constitutionally cognizable liberty interest."    See Harper v.

Showers, 174 F.3d 716, 719 (5th Cir. 1999).

     Petitt argued in the district court that his records

continued to reflect that his status had been changed because he

had used or possessed narcotics.   Petitt has waived this argument

by failing to assert it on appeal.    See Brinkmann v. Dallas

County Deputy Sheriff Abner, 813 F.2d 744, 748 (5th Cir. 1987).

     Because the appeal is frivolous, it is DISMISSED.     See

Howard v. King, 707 F.2d 215, 220 (5th Cir. 1983); 5th Cir.

R. 42.2.   The dismissal of the appeal as frivolous and the

dismissal of the complaint as frivolous by the district court

each count as a strike for purposes of 28 U.S.C. § 1915(g).

Petitt now has two strikes.    See Adepegba v. Hammons, 103 F.3d

383, 387-88 (5th Cir. 1996).   We caution Petitt that, once he

accumulates three strikes, he will not be permitted to proceed in

forma pauperis in any civil action or appeal filed while he is

incarcerated or detained in any facility unless he is under

imminent danger of serious physical injury.    See 28 U.S.C.

§ 1915(g).

     APPEAL DISMISSED; SANCTION WARNING ISSUED.
