AUSTIN, Texas -- Texas quarterback David Ash suffered a strained hamstring and is day to day, a source inside the program told ESPN's HornsNation.
Texas players are not scheduled to report until Aug. 5. While the hamstring might limit Ash's production at the start of camp, he is not expected to be limited as Texas progresses through the four weeks of camp.
Ash and junior Case McCoy are both vying for the Longhorns' starting quarterback job. Texas coach Mack Brown has insisted the competition is even despite speculation by many that Ash has the upper hand.
Ash played in 13 games (six starts) last season. He finished the year 98 of 173 for 1,068 yards with eight interceptions and four touchdowns.
McCoy had five starts. He was 89 of 145 for 1,045 yards with four interceptions and seven touchdowns.
Brown said earlier this week he is unsure when there would be some separation between the two quarterbacks. But he did allude to the fact that it would be the players, not the coaches, who eventually forced a separation.
"I've got 37 years that says it will probably happen, one way or the other," Brown said. "And usually the players will choose them for you if not. You bring in key players and ask what they think.
"But usually somebody will tweak an ankle or somebody will have a sore shoulder, and it may not just be by performance that it separates. If it doesn't separate, you choose one to start the game. If he doesn't play well, you put the other one in."
Texas does have a third option at QB in freshman Connor Brewer. But, despite the fact Brewer went through spring practice, Brown would prefer to redshirt him.
