________________________ Appeal from the United States District Court for the Middle District of Alabama

________________________ ( March 4, 2019 ) Before TJOFLAT, JORDAN, and ANDERSON, Circuit Judges.
PER CURIAM:

Case: 18-12519 Date Filed: 03/04/2019 Page: 1 of 32 Cedric Foster pled guilty to one count of conspiracy to distribute and possess with intent to distribute in excess of five hundred grams of cocaine hydrochloride, in violation of 21 U.S.C. §§ 841(a)(1), 846. He was sentenced to 135 months’ imprisonment. On appeal, he argues that the district court erred by increasing his offense level by eight levels under U.S.S.G. § 1B1.3(a)(2) and by two levels under U.S.S.G. § 2D1.1(b)(15). In its brief to our Court, the go vernment contends that Foster’s plea agreement contain s a valid and enforceable sentence appeal waiver and request s that we dismiss Foster’s appeal on that basis.
We review the validity of a sentence appeal waiver de novo

. United States v. Johnson , 541 F.3d 1064, 1066 (11th Cir. 2008). A sentence appeal waiver will be enforced if it was made knowingly and voluntarily. United States v. Bushert , 997 F.2d 1343, 1351 (11th Cir. 1993). To establish that the waiver was made knowingly and voluntarily, the government must show either that: (1) the district court specifically questioned the defendant about the waiver during the plea colloquy; or (2) the record makes clear that the defendant otherwise understood the full significance of the waiver. Id. Nothing forbids the government from raising the sentence appeal waiver for the first time in its appellate brief, rather than by motion in advance of its brief. Cf. United States v. Lopez , 562 F.3d 1309, 1313 (11th Cir. 2009) (holding that we will

Case: 18-12519 Date Filed: 03/04/2019 Page: 2 of 33 not en force sua sponte the time requirements of Fed. R. App. P. 4(b) for filing a notice of appeal in criminal case, but the issue may be raised for the first time in the government’s brief on appeal if not raised on motion). “An appeal waiver includes the waiv er of the right to appeal difficult or debatable legal issues or even blatant error.” United States v. Grinard

- Henry , 399 F.3d 1294, 1296 (11th Cir. 2005). Further, even “[a] vigorous dispute about an issue during the sentencing proceedings does not pres erve that issue for appeal when the terms of the appeal waiver do not except it from the waiver.” United States v. Bascomb , 451 F.3d 1292, 1296 (11th Cir. 2006)

. We do not address Foster’s arguments on the merits because his plea agreement contained a va lid sentence appeal waiver which he knowingly and voluntarily entered into, and his plea colloquy establishes that he understood the nature and extent of the appeal waiver and agreed to it. See Bushert , 997 F.2d at 1351 . Because none of the appeal waiver ’s exceptions apply, we grant the government’s request to dismiss Foster’s appeal. APPEAL DISMISSED.
