MEMORANDUM

California state prisoner Andrew Kwasi Donkor appeals pro se from the district court’s judgment dismissing his 42 U.S.C. § 1983 action alleging deliberate indifference to his serious medical needs and due process violations. We have jurisdiction under 28 U.S.C. § 1291 . We review de novo. Resnick v. Hayes, 213 F.3d 443, 447 (9th Cir. 2000) (dismissal under 28 U.S.C. § 1915A); Dominguez v. Miller, 51 F.3d 1502 , 1508 n.5 (9th Cir. 1995) (dismissal under Fed. R. Civ. P. 8). We affirm.

In his opening brief, Donkor failed to challenge any of the district court’s grounds for dismissal of the operative complaint, and therefore Donkor waived any such challenge. See Indep. Towers of Wash. v. Washington, 350 F.3d 925 , 929 (9th Cir. 2003) (“[W]e will not consider any claims that were not actually argued in appellant’s opening brief.”); Smith v. Marsh, 194 F.3d 1045, 1052 (9th Cir. 1999) (“[Arguments not raised by a party in its opening brief are deemed waived.”).

Even if Donkor had not waived this challenge, the district court properly dismissed Donkor’s action because the allegations in his third amended complaint were prolix, difficult to decipher, and failed to indicate how the named defendants violated Donkor’s constitutional rights. See Fed. R. Civ. P. 8(a)(2) (stating that complaint must contain “a short and plain statement of the claim showing that the pleader is entitled to relief’); McHenry v. Renne, 84 F.3d 1172, 1179 (9th Cir. 1996) (Rule 8 is an independent ground for dismissal and requires each averment of a pleading to be simple, concise, arid direct in stating which defendant is liable to the plaintiff for which wrong).

AFFIRMED.
