Teddy Wayne Solomon, federal prisoner #25882-077, appeals the district court’s denial of his supplemental 18 U.S.C. § 3582 motion to modify his term of imprisonment. Solomon’s motion challenging the constitutionality of his sentence, which was filed after the conclusion of his direct appeal and 28 U.S.C. § 2255 motion, is an unauthorized motion. See United States v. Early, 27 F.3d 140, 142 (5th Cir. 1994). Accordingly, Solomon’s appeal is DISMISSED for lack of jurisdiction.
