MEMORANDUM **

Jorge Alejandro Gutierrez appeals from the 188-month sentence imposed following his guilty-plea conviction for possession with intent to distribute methamphetamine, in violation of 21 U.S.C. § 841(a)(1) and (b)(1)(B). We have jurisdiction under 28 U.S.C. § 1291, and we affirm in part and dismiss in part.

Gutierrez contends that his sentence violates the Eighth Amendment’s prohibition against cruel and unusual punishment because it is grossly disproportionate to his offense. This contention lacks merit. See United States v. Jensen, 425 F.3d 698, 708 (9th Cir. 2005) (rejecting an Eighth Amendment disproportionality challenge to a life sentence for a defendant convicted of possession with intent to distribute methamphetamine).

Gutierrez further contends that his sentence is substantively unreasonable. As Gutierrez has conceded, however, his plea agreement includes a valid appeal waiver which precludes us from addressing this contention.

AFFIRMED in part; DISMISSED in part.
