Texas QB David Ash out vs. Ole Miss

AUSTIN, Texas -- Texas officially has ruled out quarterback David Ash for the Longhorns' game against No. 25 Ole Miss on Saturday, the school announced Friday.

Ash suffered head and right shoulder injuries in the fourth quarter against BYU last Saturday and had not been practicing this week. Texas coach Mack Brown had said Wednesday that Ash's status would likely be a game-time decision.

With Ash out, Case McCoy will start at quarterback for Texas. The senior will be making his seventh career start and has thrown for 1,831 yards and 13 touchdowns with seven interceptions in his career.

"If Case is the starter, the guys trust Case," Brown said on Wednesday. "He's a fourth-year senior. He has been around a long time, and it's not like we'd be starting a guy that has never been out there. There won't be panic if David is not ready to go. They will be excited about Case."

Texas has declined to reveal Ash's specific injuries and whether he suffered a concussion, but Ash's status had been considered day-to-day entering the week. He's thrown for 594 yards and six touchdowns and also rushed for 125 yards and a touchdown through two games.

McCoy left the program for 10 weeks this summer for a mission trip to Peru, but he returned and beat out true freshman quarterback Tyrone Swoopes for the backup job in fall camp.

If McCoy is injured, the Longhorns could turn to Swoopes, a touted four-star dual-threat quarterback who has yet to take a snap. He enrolled early in the spring, but the Texas coaching staff would prefer to redshirt him this season if possible.

"I've got a tremendous amount of confidence in Case, and his team has a tremendous amount of confidence in him," Texas co-offensive coordinator Major Applewhite said Monday. "We'd like to play Case. We'd like to redshirt Tyrone Swoopes. Obviously, injuries will dictate that."

Ash has made 20 career starts and only missed one game in the 2012 season, because of a rib injury. McCoy earned the start and threw for 314 yards with two touchdowns and two interceptions in a 42-24 road loss at Kansas State last December.
