Damion Stevenson appeals the sentence the district court
We decline to consider Stevenson's ineffective-assistance claims on direct appeal. See United States v. Hernandez, 281 F.3d 746, 749 (8th Cir. 2002) (noting an ineffective-assistance claim is generally not cognizable on direct appeal and is properly raised in a 28 U.S.C. § 2255 action). We also conclude the appeal waiver is valid, enforceable, and applicable to Stevenson's challenge to his sentence. See United States v. Scott, 627 F.3d 702, 704 (8th Cir. 2010) (reviewing validity and applicability of appeal waiver de novo); United States v. Andis, 333 F.3d 886, 889-92 (8th Cir. 2003) (en banc) (enforcing appeal waiver if appeal falls within scope of waiver, defendant knowingly and voluntarily entered into plea agreement and waiver, and it would not result in miscarriage of justice).
Further, having independently reviewed the record under Penson v. Ohio, 488 U.S. 75 (1988), we find no nonfrivolous issues for appeal outside the scope of the appeal waiver. Accordingly, we grant counsel leave to withdraw and dismiss this appeal.
