Texas junior quarterback David Ash has been ruled out for Saturday's Red River Shootout against Oklahoma as a "result of lingering effects of his head injury" per Texas head athletic trainer for football Kenny Boyd.
Ash has completed 53-of-87 passes for 760 yards and seven touchdowns to two interceptions this year. And he's rushed 31 times for 152 yards and a score. But he's missed extensive time this season with a head injury he suffered against BYU. Ash sat out Texas's third game against Ole Miss, returned for a half against Kansas State and then missed the second half of that contest. On Thursday, Ash didn't make the trip up to Ames for the Iowa State game.
Case McCoy, who is expected to start against Oklahoma, has manned the quarterback spot in Ash's absence. He has actually thrown more passes than Ash, but hasn't been nearly as effective, completing 62-of-102 throws for 574 yards and two touchdowns to no interceptions, while providing no running threat.
Texas's coaches have talked about preparing true freshman Tyrone Swoopes to play, but he has yet to see any action in his inaugural season on campus.
Ash's injury update wasn't the only one announced by Boyd. Cornerback Sheroid Evans will miss the rest of the season after sustaining a knee injury against Iowa State. Boyd said that an MRI conducted on the injury revealed a tear of Evans's ACL.
