Salvador Barajas, Jr., appeals his guilty plea conviction and sentence for possessing with intent to distribute 500 grams or more of a mixture containing methamphetamine, in violation of 21 U.S.C. § 841(a)(1), (b)(l)(A)(viii). Barajas argues that the factual basis for his guilty plea was inadequate because it did not establish that he knew the type and quantity of the controlled substance involved in his offense.

However, Barajas has filed an unopposed motion for summary disposition correctly conceding that this issue is foreclosed by United States v. Betancourt, 586 F.3d 303 (5th Cir. 2009), and explaining that he has raised the issue only to preserve it for possible further review. Accordingly, because summary disposition is appropriate, see Groendyke Transp., Inc. v. Davis, 406 F.2d 1158, 1162 (5th Cir. 1969), Barajas’s motion is GRANTED. The district court’s judgment is AFFIRMED.
