Ivery Traveno Williams, Texas prisoner No. 183233, appeals the dismissal of his civil rights complaint as frivolous and for failure to state a claim. Williams moves for appointment of appellate counsel and he requests permission to file a supplemental brief and supporting exhibits. The motions are denied.

Proceeding pro se and in forma pauperis (IFP), Williams filed suit challenging the constitutionality of the procedures used to determine his eligibility for parole and alleging that Texas Department of Criminal Justice (TDCJ) Officers McCadden and Whitaker and Sergeant Ferguson had subjected him to false disciplinary charges, harassment, and retaliation.

The district court did not err in determining that Williams’s claims concerning the procedures used to determine his eligibility for parole do not involve a constitutional right. See Madison v. Parker, 104 F.3d 765, 768 (5th Cir. 1997); Orellana v. Kyle, 65 F.3d 29, 31-32 (5th Cir. 1995). We likewise find no error in the determi *481 nation that Williams’s allegations concerning Officers McCadden and Whitaker and Sergeant Ferguson do not state a constitutional violation. Williams’s claims concerning the alleged denial of outdoor exercise are frivolous.

In addition to the instant complaint, at least two prior complaints filed by Williams have been dismissed as frivolous by the district court. In Williams v. Garrett, No. 3:04-CV-548-R, 2004 WL 877105 (N.D.Tex. May 10, 2004), the district court dismissed as frivolous a petition for writ of mandamus filed by Williams and we dismissed the appeal for want of prosecution. In Williams v. Wilkinson, 78 Fed.Appx. 384 (5th Cir. 2003), we affirmed the district court’s dismissal as frivolous of a civil rights complaint filed by Williams.

Consequently, Williams has accumulated at least three strikes under 28 U.S.C. § 1915(g). See Adepegba v. Hammons, 103 F.3d 383, 387-88 (5th Cir. 1996). Williams is therefore barred from proceeding IFP 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).

AFFIRMED; MOTIONS DENIED; 28 U.S.C. § 1915(g) BAR IMPOSED.
