Nathaniel Singleton, a former Texas prison inmate, appeals the dismissal of his civil rights lawsuit against prison guard Bernard Sweet. The district court dismissed Singleton’s case without prejudice pursuant to 42 U.S.C. § 1997e(a) for failure to exhaust administrative remedies. Dismissals for failure to exhaust administrative remedies under § 1997e(a) are reviewed de novo. Powe v. Ennis, 177 F.3d 393, 394 (5th Cir. 1999).

The district court concluded that the Step 1 and 2 grievances that Singleton produced involved an appeal of a disciplinary procedure and did not relate to the excessive force claim that Singleton raised in his complaint. A “grievance should be considered sufficient to the extent that the grievance gives officials a fair opportunity to address the problem that will later form the basis of the lawsuit.” Johnson v. Johnson, 385 F.3d 503, 517 (5th Cir. 2004). The record shows that the investigating officer responded to Singleton’s Step 2 grievance in part by opening an investigation of Singleton’s excessive force allegations. Thus, it is unclear whether the grievance forms on which Singleton relies *373 relate only to the appeal of a disciplinary procedure.

Nevertheless, we need not reach the question whether Singleton’s grievance was sufficient to provide notice of this claim, as we affirm the dismissal for failure to exhaust on an alternative ground. See Underwood v. Wilson, 151 F.3d 292, 296 (5th Cir. 1998). At the time Singleton filed his complaint, he had not completed the Texas Department of Criminal Justice grievance process. Generally, an inmate must exhaust his administrative remedies before filing a § 1983 lawsuit. Wendell v. Asher, 162 F.3d 887, 890-91 (5th Cir. 1998). Because Singleton did not do so, the district court did not err in dismissing the case. The judgment of the district court is AFFIRMED.
