Brian Brohm brought Louisville back from 17 points down in the second half, with the Cardinals (5-5, 2-3 Big East) tying it on Art Carmody's 37-yard field goal with 3:05 left. White then capped a 65-yard drive with his scoring run up the left sideline.
Brohm, who broke his own Big East record with his seventh 300-yard game of the season, threw a desperation pass that Antonio Lewis intercepted at the West Virginia 7.
