Brandon M. Hollywood appeals his guilty plea conviction and sentence for aiding and abetting the distribution of and distributing less than five grams of crack cocaine in violation of 18 U.S.C. § 2 and 21 U.S.C. § 841(a)(1).

Hollywood contends that the district court erred when it denied his motion to withdraw his guilty plea. “[A] district court may, in its discretion, permit withdrawal [of a guilty plea] before sentencing if the defendant can show a ‘fair and just reason.’ ” United States v. Powell, 354 F.3d 362, 370 (5th Cir. 2003) (citing Fed. R.Crim.P. 11(d)(2)); see also United States v. Carr, 740 F.2d 339, 343-44 (5th Cir. 1984). The district court did not abuse its discretion when it denied Hollywood’s motion to withdraw his guilty plea. See Powell, 354 F.3d at 370.

Further, Hollywood contends that the district court erred in determining the quantity of drugs attributable to him as relevant conduct. He also contends that the district court erred when it increased his base offense level pursuant to U.S.S.G. § 2Dl.l(b)(l) for possession of a weapon in connection with a drug-trafficking offense. Hollywood’s sentence was not determined based on the drug quantity calculation or the two-level increase pursuant to U.S.S.G. § 2Dl.l(b)(l). Instead, Hollywood’s sentence was determined based on his status as a career offender pursuant to U.S.S.G. § 4B1.1. Therefore, these arguments are irrelevant.

Accordingly, the district court’s judgment is AFFIRMED.
