Austin, Texas ? Garrett Gilbert is out as the starting quarterback at No. 23 Texas. The Longhorns will go with Case McCoy and David Ash when they play at UCLA.

Texas coach Mack Brown announced the expected switch Monday, two days after McCoy and Ash came off the bench in the second quarter and rotated snaps while leading the Longhorns to a come-from-behind 17-16 victory over BYU.

Ash, a freshman who is still primarily a runner, shook up BYU’s defense by directing an option attack that took advantage of Texas’ speed.

McCoy, a sophomore whose older brother is former Texas quarterback Colt McCoy, at this point is the better passer and took most of the snaps on the drive to the winning touchdown in the fourth quarter.

Texas (2-0) also announced another big change on offense, with freshman Malcolm Brown listed as the starting tailback ahead of senior Fozzy Whittaker. Brown leads Texas in rushing with 154 yards on 30 carries.

“The one thing we’ve committed to ourselves and our team is that if something’s not working, change it,” Mack Brown said. “It’s a product of are you moving the ball? Are you scoring points? As a staff, we said let’s try something else. The combination of David and Case worked.”
