MEMORANDUM **

Federal prisoner Reginald L. McCoy appeals pro se the district court’s judgment dismissing for failure to state a claim his civil rights action alleging that prison officials violated his Eighth Amendment rights and that he was wrongfully disciplined. We have jurisdiction pursuant to 28 U.S.C. § 1291. We review de novo, Resnick v. Hayes, 213 F.3d 443, 447 (9th *271Cir. 2000) (dismissals under 28 U.S.C. § 1915A); Barren v. Harrington, 152 F.3d 1193, 1194 (9th Cir. 1998) (order) (dismissals under 28 U.S.C. § 1915(e)), and we affirm.

The district court properly dismissed McCoy’s claim alleging mental or emotional injury because he failed to allege that he suffered anything more than a de minimis physical injury. See 42 U.S.C. § 1997e(e); Oliver v. Keller, 289 F.3d 623, 627-29 (9th Cir. 2002).

The district court properly dismissed McCoy’s claim that he was wrongfully disciplined because a judgment in his favor would imply the invalidity of the deprivation of his good-time credits. See Edwards v. Balisok, 520 U.S. 641, 646, 117 S.Ct. 1584, 137 L.Ed.2d 906 (1997); Martin v. Sias, 88 F.3d 774, 775 (9th Cir. 1996) (order).

AFFIRMED.
