AUSTIN, Texas -- Texas quarterback David Ash has been cleared to participate in spring drills.

Ash was the starter last season before sustaining a concussion in the second game against BYU. He returned two weeks later and played one half against Kansas State, but was removed at halftime and didn't return for the rest of the season. Case McCoy started the final nine games.

Doctors had advised Ash to stay away from Texas games at several points during the season to avoid the stadium lights and large crowds. Ash did attend Texas' game against Oregon in the Alamo Bowl.

Saturday night's statement from athletic trainer Kenny Boyd said Ash has now been cleared to fully participate in offseason workouts and spring drills.
