PER CURIAM:
Gregory McPherson, Texas prisoner # 1437871, moves for leave to proceed in forma pauperis (“IFP”) in his appeal of the dismissal of his 42 U.S.C. § 1983 civil rights lawsuit. By moving for IFP status, McPherson is challenging the district court’s certification that the appeal is not taken in good faith. See Baugh v. Taylor, 117 F.3d 197, 202 (5th Cir.1997); Fed. R.App. P. 24(a).
McPherson’s brief contends only in general terms that his claims are not frivolous. He does not address, however, the certification that his appeal was not taken in good faith or any of the district court’s reasons, see Baugh, 117 F.3d at 202, so his challenge to the certification is deemed abandoned, see Brinkmann v. Dallas Cnty. Deputy Sheriff Abner, 813 F.2d 744, 748 (5th Cir.1987). Thus, McPherson has not shown that his appeal involves “legal points arguable on their merits (and therefore not frivolous).” Howard v. King, 707 F.2d 215, 220 (5th Cir.1983) (internal quotation and citation omitted).
The motion to proceed IFP on appeal is DENIED, and the appeal is DISMISSED as frivolous. See Baugh, 117 F.3d at 202 & n. 24; 5th Cir. R. 42.2. The dismissal by the district court and the dismissal of the appeal both count as strikes pursuant to 28 U.S.C. § 1915(g). See Adepegba v. Hammons, 103 F.3d 383, 385-87 (5th Cir. 1996). Thus, McPherson is cautioned that if he accumulates three strikes under § 1915(g), he will not be able to proceed IFP in any civil action or appeal filed while he is incarcerated or detained in any facility unless he is under imminent danger of serious physical injury. See § 1915(g).
Pursuant to 5th Cir. R. 47.5, the court has determined that this opinion should not be published and is not precedent except under the limited circumstances set forth in 5th Cir. R. 47.5.4.
