Texas (2-2) will play Thursday night without quarterback David Ash, Longhorns coach Mack Brown said Wednesday.
Case McCoy will start in place of Ash against Iowa State.
Ash suffered a head injury in Week 2 against BYU, sat out the following week's loss to Ole Miss and returned to play Sept. 21 against Kansas State. But Ash was injured in that game and replaced by McCoy.
