Ash has been held out of practice since leaving in the fourth quarter of last week’s loss against BYU with head and shoulder injuries. The school said senior Case McCoy will start.
Texas coach Mack Brown had said Ash could be a game-time decision. Longhorns athletic trainer Kenny Boyd announced in a statement that Ash will not play.
Ash has accounted for seven touchdowns for the Longhorns (1-1). Freshman Tyrone Swoopes will backup McCoy.
