Lonnie Donnelly, Mississippi prisoner # K1304, appeals the magistrate judge’s dismissal as frivolous and for failure to state a claim of his 42 U.S.C. § 1983 complaint against defendants Jamie Darby and *824 Jamie Clark. Donnelly had previously voluntarily dismissed his claims against defendants Scott Fitch and Doug Sproat. Donnelly asserts that Darby and Clark used excessive force against him by spraying mace in his face and denied him medical care after the spraying.

Donnelly has not established that the delay he suffered in receiving medical care was due to deliberate indifference or that he suffered substantial harm as a result of the delay. See Mendoza v. Lynaugh, 989 F.2d 191, 195 (5th Cir. 1993). The magistrate judge’s dismissal of the claims is therefore AFFIRMED.

With respect to the excessive-force claims, the magistrate judge erred in concluding that Donnelly engaged in a verbal confrontation with Clark or Darby that would have excused the spraying of mace. See Calhoun v. Hargrove, 312 F.3d 730, 733 (5th Cir. 2002). However, this error is harmless. As Donnelly admits that he received a disciplinary conviction arising from the same action of which he complains now, his claims are barred. See Edwards v. Balisok, 520 U.S. 641, 648-49, 117 S.Ct. 1584, 137 L.Ed.2d 906 (1997); Heck v. Humphrey, 512 U.S. 477, 487, 114 S.Ct. 2364, 129 L.Ed.2d 383 (1994); Hainze v. Richards, 207 F.3d 795, 798-99 (5th Cir. 2000). Therefore, the claim was frivolous and could be dismissed. See Siglar v. Hightower, 112 F.3d 191, 193 (5th Cir. 1997), Accordingly, the judgment of the magistrate judge is AFFIRMED.

Donnelly has moved for appointment of counsel. This motion is DENIED.
