Matthew Caldwell came into the game at quarterback and put the finishing touches on the Longhorns' victory.

Texas, which was ranked 20th in the latest AP Poll, faces No. 9 Vanderbilt this Saturday. Caldwell would likely get the start if Manning doesn't clear the concussion protocol.

Manning has completed 60.9% of his passes this season for 15 touchdowns to six interceptions.
