David Ash was the hero in last year's game against Oklahoma State, but when the Longhorns face the Cowboys this year, Ash will not be on the field.
Ash has yet to be medically cleared following a head injury he suffered nearly two months ago and will miss his sixth straight game when Texas hosts Oklahoma State this Saturday.
"They're working him off the field and they haven't released him yet to us but right now they think he's making progress," Texas head coach Mack Brown said. "He will not be playing this weekend, in my estimation, since he hasn't been released by today. I think he'll need to be released and then have a week's practice before he could play the next week."
Ash completed 30 of 37 passes for 307 yards and three touchdowns in a 41-36 victory in Stillwater last season, helping Texas improve to 4-0. He hit D.J. Grant for 29 yards on a 4th-and-6 in the final moments of the game to set up a game-winning touchdown run by Joe Bergeron.
Junior offensive tackle Josh Cochran will also miss his sixth straight game with a shoulder injury. His backup, sophomore Kennedy Estelle, who has started in his place in each of the previous five games, is questionable with a hip injury that caused him to exit Texas' 47-40 overtime win over West Virginia last Saturday.
That means the Longhorns will be without at least five starters this weekend as sophomore running back Johnathan Gray and senior defensive tackle Chris Whaley were lost for the rest of the year after suffering season-ending injuries against West Virginia. Gray tore his right Achilles tendon and Whaley hurt his knee. Both injuries will require surgery.
