MEMORANDUM **

Jean Miller appeals pro se from the district court’s judgment for defendants after a jury trial in Miller’s 42 U.S.C. § 1983 action alleging excessive force during her arrest. We have jurisdiction under 28 U.S.C. § 1291. We review for an abuse of discretion the trial court’s conduct during trial. Price v. Kramer, 200 F.3d 1237, 1252 (9th Cir. 2000). We affirm.

To the extent that Miller seeks to challenge the sufficiency of the evidence used by the jury in reaching its decision, she forfeited the right to do so by failing to file a motion under Fed.R.Civ.P. 50(a) or (b). See Nitco Holding Corp. v. Boujikian, 491 F.3d 1086, 1088-89 (9th Cir. 2007) (holding that “a party procedurally defaults a civil appeal based on the alleged insufficiency of the evidence to support the verdict if it fails to file a post-verdict motion for judgment notwithstanding the verdict”).

We do not consider Miller’s contention that a member of the jury was biased because it was raised for the first time on appeal, and its consideration is not “necessary to prevent manifest injustice.” Travelers Prop. Cas. Co. of Am. v. ConocoPhillips Co., 546 F.3d 1142, 1146 (9th Cir. 2008).

Miller’s remaining contentions, including allegations of incompetence and bias by the district court judge and fraud upon the court, are unpersuasive.

Miller’s motions for a further extension of time to file a supplemental reply brief are denied.

AFFIRMED.
