West Virginia struggled to move the ball much of the game, but the Mountaineers looked impressive on a 91-yard drive capped by Sims' 1-yard run for a 26-16 lead midway through the third quarter.
McCoy then found Mike Davis for a 49-yard TD pass, and the pair combined on a 29-yard pass on Texas' next drive to help set up Joe Bergeron's 8-yard scoring run to put the Longhorns ahead 30-26 entering the fourth quarter.
A facemask penalty on the ensuing kickoff gave West Virginia the ball near midfield, and Dreamius Smith capped the short drive with an 8-yard TD run.
