MEMORANDUM **

Shane I. Sopher, an Oregon state prisoner, appeals pro se from the district court’s order dismissing pursuant to 28 U.S.C. § 1915A his 42 U.S.C. § 1983 action alleging violations of the Due Process, Equal Protection, and Ex Post Facto Clauses. We have jurisdiction pursuant to 28 U.S.C. § 1291. We review de novo dismissals on statute of limitations grounds, Jones v. Blanas, 393 F.3d 918, 926 (9th Cir. 2004), and we vacate and remand.

Because the district court dismissed the complaint on screening, without leave to amend, Sopher had no opportunity to ar*521gue that the statute of limitations should have been equitably tolled. See Cervantes v. City of San Diego, 5 F.3d 1273, 1276-77 (9th Cir. 1993) (dismissal on statute of limitations grounds disfavored where matters outside the complaint may not be considered and where equitable tolling may apply); see also Chaney v. Fields Chevrolet Co., 264 Or. 21, 26-27, 503 P.2d 1239 (1972) (indicating that fraudulent concealment is recognized in Oregon as basis for tolling the statute of limitations). We remand for the district court to determine in the first instance whether equitable tolling applies to the circumstances of this case.

The parties shall bear their own costs on appeal.

VACATED and REMANDED.
