AUSTIN, Texas -- Texas got some much-needed good news on the eve of its Big 12 opener against Kansas State.

Quarterback David Ash, who suffered a concussion two weeks ago, will start against Kansas State on Saturday after team doctors cleared him, the school announced Friday.

Ash, who suffered the concussion during the Longhorns' 40-21 loss to BYU on Sept. 7, resumed practicing with the team Wednesday after being held out of Texas' 41-23 loss to Ole Miss last week.

Three other starters on Texas' offense are still questionable Saturday. Receiver Mike Davis (ankle), offensive tackle Josh Cochran (shoulder) and offensive guard Mason Walters (knee) were all day to day this week because of injuries suffered against Ole Miss.

Those three will be game-time decisions, as is linebacker Dalton Santos. The sophomore has a leg injury but could make his first start of the season. Starting tight end Greg Daniels and running back/receiver Daje Johnson were ruled out earlier in the week.

Texas had been handling Ash's recovery cautiously, and he did not attend the loss to Ole Miss because of the concussion. Senior Case McCoy earned his seventh career start in his place.

The return of Ash should make it more unlikely that the Longhorns will use true freshman Tyrone Swoopes against the Wildcats. The dual-threat quarterback had planned to redshirt this season, but Texas coach Mack Brown said Wednesday that he would look at giving Swoopes playing time if Ash couldn't make the start.
