MEMORANDUM**
Thomas Henderson, a California state prisoner, appeals pro se the district court’s judgment dismissing for failure to exhaust his administrative remedies in 42 U.S.C. § 1983 action, alleging defendants violated his constitutional rights. We have jurisdiction pursuant to 28 U.S.C. § 1291. We review de novo, Barren v. Harrington, 152 F.3d 1193, 1194 (9th Cir.1998) (order), and we vacate and remand.
The district court dismissed Henderson’s action pursuant to 42 U.S.C. § 1997e(a) because the exhibits attached to the complaint did not establish that Henderson exhausted his administrative remedies. We have since held that exhaustion under 42 U.S.C. § 1997e(a) is an affirmative defense rather than a pleading requirement. See Wyatt v. Terhune, 315 F.3d 1108,1119 (9th Cir.2003). Accordingly, we vacate the district court’s judgment and remand the matter for further proceedings.
VACATED and REMANDED.
