Texas had a huge first-and-goal inside the two-minute warning but had to settle for a 21-yard field goal in the 28-20 loss.
The Longhorns did not recover an onside kick following the field goal, but their fortunes almost turned when Oklahoma quarterback Landry Jones fumbled the ball as he was sacked by Emmanuel Acho. DeMarco Murray recovered the ball for the Sooners.
After Oklahoma was forced to punt the ball away with 1:08 remaining, Aaron Williams fumbled the punt return, and it was recovered by the Sooners to seal the victory.
Early in the third quarter, the Sooners added to their lead in the fourth quarter with an acrobatic, 20-yard touchdown run by DeMarco Murray. Murray also scored the first Oklahoma touchdown.
The Longhorns quickly struck back with a five-yard touchdown run by Cody Johnson, whose 33-yard reception earlier in the drive put Texas within striking distance.
