Lubbock, Texas Hodges Mitchell ran for 229 yards and two touchdowns and Kris Stockton tied a school record with five field goals as No. 20 Texas beat Texas Tech, 29-17, on Saturday night.
The Longhorns suffered a major blow, however, when quarterback Major Applewhite injured his right knee in the fourth quarter.
"I'm not sure yet, it's either a partial or all the way torn ACL," Applewhite said.
Coach Mack Brown said Applewhite would be evaluated when the team returned to Austin. The Longhorns' next game is Saturday at Kansas.
"Major was walking at the end of the game on the sideline and felt good, but I'm not a doctor," Brown said. "The word I got, it was a sprain. Hopefully, it won't be that bad."
Texas (7-2, 5-1 Big 12) struggled to get the ball in the end zone in the first half Saturday, keeping the pass-happy Red Raiders (6-4, 2-4) in the game.
The Longhorns never seemed in control until Mitchell's 6-yard TD run with 2:07 left in the third quarter. Wes Welker mishandled a punt, and Mitchell needed just two runs from the 14 to put the Longhorns ahead 26-17.
Texas has won four straight games since the embarrassing 63-14 loss to top-ranked Oklahoma, which had 534 total yards, including 289 passing.
The Longhorns were much more successful against the Sooners-inspired Texas Tech offense. First-year Tech coach Mike Leach was the offensive coordinator at Oklahoma last season.
Texas Tech was ahead 17-16 when Ricky Williams scored on a 1-yard run with 10:35 to go in the third quarter. The score came two plays after linebacker John Norman intercepted Applewhite's pass and returned it 11 yards to the 14.
Applewhite made up for the miscue, moving the Longhorns 55 yards in 10 plays for Stockton's 36-yard field goal that put Texas ahead to stay.
