Nicholas Quantel Roberson, federal prisoner # 56146-180, appeals the denial of his 18 U.S.C. § 3582(c)(2) motion for reduction of the 240-month sentence he is serving following his guilty plea to possession with *328 intent to distribute more than 50 grams of crack cocaine. Roberson argues pursuant to U.S.S.G. § 1B1.10 and Amendment 706 to the Sentencing Guidelines that he is entitled to resentencing. We review the district court’s ruling for abuse of discretion. United States v. Townsend, 55 F.3d 168, 170 (5th Cir. 1995).

In the circumstance where a prisoner’s guidelines range has subsequently been lowered as a result of a listed amendment to the Guidelines Manual, the court may reduce the term of imprisonment pursuant to § 3582(c)(2) only if such a reduction is consistent with policy statement § 1B1.10. § lB1.10(a). Amendment 706 is listed as a “covered amendment,” see § lB1.10(c); however, “[eligibility for consideration under [§ 3582(c)(2) ] is triggered only by an amendment ... that lowers the applicable guideline range.” § 1B1.10, cmt. (n.l).

Based upon his guilty plea in the instant case to possession of more than 50 grams of crack cocaine and, additionally, the penalty enhancement he received for his 2002 Texas felony drug offense, Roberson faced a mandatory minimum 20-year term of imprisonment. See 21 U.S.C. § 841(b)(l)(A)(iii). A guidelines sentence may not be imposed that is less than the statutorily required minimum sentence. § 5G1.1(c)(2). The guidelines amendment would therefore not have the effect of lowering his applicable guidelines range, and the district court’s denial of his motion was not an abuse of discretion. Cf. United States v. Pardue, 36 F.3d 429, 431 (5th Cir. 1994).

AFFIRMED.
