OPINION
Joey Caulder appeals his conviction and 121-month sentence for conspiring to distribute methamphetamine. See 21 U.S.C. § 846 (1994). On appeal, Caulder contends his trial counsel’s failure to seek a downward departure under United States *254Sentencing Guidelines Manual § 5H1.4, p.s. (2000) constitutes ineffective assistance of counsel in violation of the Sixth Amendment. See Strickland v. Washington, 466 U.S. 668, 690-91, 694, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984). However, such a claim is not cognizable on direct appeal unless counsel’s ineffectiveness appears plainly on the record. United States v. King, 119 F.3d 290, 295 (4th Cir.1997). Because the record does not on its face demonstrate Caulder received ineffective assistance of counsel, we affirm.
In relevant part, § 5H1.4 states that “[pjhysical condition ... is not ordinarily relevant in determining whether a sentence should be out-side the applicable guideline range.” Nevertheless, “an extraordinary physical impairment may be a reason to impose a sentence below the applicable guideline range.” Id. Caulder argues the bilateral paresis he suffers as a result of a 1982 diving accident constitutes such an impairment, and thus that his attorney was ineffective for failing to seek a departure under this provision. However, the record on appeal does not conclusively demonstrate Caulder would have received such a downward departure had his attorney requested it. Accordingly, we reject Caulder’s sole assignment of error on appeal. See King, 119 F.3d at 295.
In light of the foregoing, Caulder’s conviction and sentence are affirmed, and we dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.
AFFIRMED.
