Ash didn't practice all of last week, and wasn't on the sidelines for the Ole Miss game, just seven days after suffering head and shoulder injuries against BYU. The former injury appeared to be the more serious, with doctors recommending that Ash not attend the game against the Rebels, continuing to isolate him after a week of concussion testing. The setting of a Texas game — with the bright lights, loud noises and movement — wouldn't have been an environment conducive to someone trying to recover from a concussion.
Prior to the injury, Ash had a strong start to the 2013 season, completing 39-of-62 passes (62.9 percent) for 594 yards and six touchdowns to two interceptions. He also rushed 24 times for 125 yards, an average of 5.2 yards per carry, while scoring a touchdown on the ground.
Case McCoy performed admirably in Ash's absence against Ole Miss, not turning the ball over while hitting on 24-of-36 throws for 196 yards and one touchdown and running five times for 14 yards. But the Longhorns didn't score in the second half, with McCoy completing 13-of-26 throws for 92 yards.
Texas was ranked no. 6 nationally in offensive S&P+ in the first two games, and fell to No. 13 after Ash's absence last week.
