Michael Short, federal prisoner # 22355-034, appeals the district court’s denial of his 18 U.S.C. § 3582(c)(2) motion for a sentence reduction pursuant to Amendments 591 and 607. He contends that the district court erroneously determined that Amendment 591 did not apply because he was not convicted of an offense referenced in U.S.S.G. § 2D1.2. In addition, Short asserts that the district court did not follow the correct procedure in calculating his original advisory guidelines range.

We review for abuse of discretion a district court’s decision whether to reduce a sentence pursuant to § 3582(c)(2). United States v. Evans, 587 F.3d 667, 672 (5th Cir. 2009). Amendments 591 and 607 did not have the effect of lowering Short’s guidelines range. Therefore, Short was not eligible for a sentence reduction under § 3582(c)(2). See Dillon v. United States, 560 U.S. 817, 826-27, 130 S.Ct. 2683, 177 L.Ed.2d 271 (2010); United States v. Anderson, 591 F.3d 789, 791 (5th- Cir. 2009); United States v. Wilson, 267 Fed.Appx. 317, 318 (5th Cir. 2008). Further, Short’s claims regarding the validity of his original sentence are not cognizable in a § 3582(c)(2) motion. See United States v. Hernandez, 645 F.3d 709, 712 (5th Cir. 2011). The district court did not abuse its discretion in denying Short’s motion. See Dillon, 560 U.S. at 826-27, 130 S.Ct. 2683.

AFFIRMED.
