MEMORANDUM **
Avon Davies, a California state prisoner, appeals pro se the district court’s judgment dismissing his 42 U.S.C. § 1983 action against prison medical officials alleging deliberate indifference to his serious medical needs. We have jurisdiction under 28 U.S.C. § 1291. We review de novo, Lopez v. Smith, 203 F.3d 1122, 1126-27 (9th Cir.2000) (en banc), and we affirm.
The district court correctly concluded that the present claim is barred by res judicata because it arises out of the same injury and the same wrongful conduct that *937Davies alleged in his prior action against the same defendants. See Olson v. Morris, 188 F.3d 1083, 1086 (9th Cir.1999). Furthermore, this court previously considered and rejected Davies’ challenge to the constitutionality of 42 U.S.C. § 1997e(a) in the related appeal, Davies v. Greenough, No. 01-17515, 42 Fed.Appx. 598, 2002 U.S.App. LEXIS 17542 (9th Cir.2002).
AFFIRMED.
