By now, Texas coach Mack Brown had almost no choice.
Gilbert completed 2 of 8 passes for 8 yards and two interceptions before being benched early in the second quarter of Saturday's 17-16 win over BYU. He was booed repeatedly coming on and off the field in Saturday's game.
McCoy, the younger brother of former UT star Colt McCoy, shared time with the mobile true freshman Ash for the rest of the game.
They combined to complete 9 of 11 passes for 92 yards.
