Lonnie Donnelly, Mississippi prisoner #K1304, appeals the magistrate judge’s dismissal of his 42 U.S.C. § 1983 complaint. The magistrate judge dismissed Donnelly’s claims regarding a denial of access to the courts for failure to state a constitutional claim. Donnelly has not established that he was unable to proceed in a court case as a result of the delays and the denial of assistance in the law library. See Lewis v. Casey, 518 U.S. 343, 349-53, 116 S.Ct. 2174, 135 L.Ed.2d 606 (1996); Brewer v. Wilkinson, 3 F.3d 816, 821 (5th Cir. 1993). Donnelly has not established that the magistrate judge erred in denying relief on this ground. See Calhoun v. Hargrove, 312 F.3d 730, 733 (5th Cir. 2002).

The magistrate judge dismissed the remainder of Donnelly’s claims because he had not established that he had exhausted his administrative remedies. The exhaustion requirement of 42 U.S.C. § 1997e(a) is mandatory. Days v. Johnson, 322 F.3d 863, 866 (5th Cir. 2003). However, a mere allegation of exhaustion without proof is sufficient to overcome dismissal. Underwood v. Wilson, 151 F.3d 292, 296 (5th Cir. 1998). Donnelly’s allegations against Scott Fitch, Diane Foy, Nichole Beranich, and W. Clemens do not sufficiently specify the exhaustion of administrative remedies, and the dismissal by the magistrate judge is AFFIRMED.

Donnelly alleges, however, that he filed an administrative appeal following his disciplinary conviction by Dana Ricks and that relief was denied on appeal. This assertion is sufficient to establish the exhaustion of administrative remedies. See id. However, Donnelly cannot establish that he is entitled to relief on this claim. See Sandin v. Conner, 515 U.S. 472, 475, 486-87, 115 S.Ct. 2293, 132 L.Ed.2d 418 (1995); Superintendent, Massachusetts Corr. Inst. v. Hill, 472 U.S. 445, 455-56, 105 S.Ct. 2768, 86 L.Ed.2d 356 (1985). Therefore, this court AFFIRMS the dismissal on this alternate ground. See Sojourner T v. Edwards, 974 F.2d 27, 30 (5th Cir. 1992).

AFFIRMED.
