Nicolas Pena appeals the 96-month sentence imposed following his guilty plea conviction for importing cocaine. He argues that the district court erred by not *374 finding that he played a minor role in the offense and sentencing him accordingly. As Pena concedes, this claim is reviewed for plain error only due to his failure to raise it in the district court. See United States v. Villegas, 404 F.3d 355, 358 (5th Cir . 2005).

Pena has failed to establish that he was less culpable than other participants in the offense. See U.S.S.G. § 3B1.2, comment. (n.5). He has not shown that the district court plainly erred in connection with his sentence. The judgment of the district court is AFFIRMED.
