Robert Lee Chavez appeals the sentence imposed by the district court following his *800 guilty-plea conviction for possession with the intent to distribute methamphetamine and aiding and abetting. Chavez argues that the district court plainly erred by assessing him a “career offender” enhancement based on his two prior Texas convictions for controlled-substance offenses.

The Government has filed a motion for summary affirmance based on the waiver-of-appeal provision in Chavez’s plea agreement. The Government asserts that Chavez knowingly and voluntarily waived his appellate rights on this issue.

Our review of the record shows that Chavez’s appeal waiver was knowing and voluntary and that, under the plain language of the plea agreement, the waiver applies to the circumstances at hand. See United States v. Burus, 433 F.3d 442, 445-46 (5th Cir. 2005); United States v. McKinney, 406 F.3d 744, 746 (5th Cir. 2005). Accordingly, Chavez’s appeal waiver bars review of the issue he seeks to raise on appeal.

The judgment of the district court is AFFIRMED, the Government’s motion for summary affirmance is GRANTED, and the Government’s motion for an extension of time is DENIED.
