Ash suffered what appeared to be a serious wrist injury late in Saturday's 63-21 loss to Oklahoma, but X-rays were negative and showed no fractures. Ash practiced and took snaps during Sunday's practice, according to the Dallas Morning News' Chuck Carlton.
The starting quarterback suffered his first truly poor game of the season against the Sooners, passing for 113 yards and two interceptions and completing just 44.8 percent of his passes. For the season, Ash is completing 71.9 percent of his passes for 1,389 yards, with eleven touchdowns and three interceptions.
The loss to the Sooners dropped the Longhorns out of the AP Top 25, although Texas was able to slip into the No. 25 spot in the latest BCS rankings.
