The No. 10 Longhorns, who lost the heart of their defense when tackle Kenneth Sims was injured, responded with pass interceptions by Bobby Johnson and Mossy Cade and a fumble recovery by William Graham in the end zone to win in Austin.
Sims, a 270-pound all-America, broke his right leg and torn ligaments in the ankle late in the first quarter, ending his college career.
Texas (7-1-1, 4-1-1 in the SWC) led, 7-0, on A.J. Jones' 29-yard run when Sims was hurt, and Texas Christian (2-6-2, 1-5-1) closed to 7-6 on field goals by Greg Porter of 25 and 24 yards. Johnson then raced in front of Reuben Jones' pass and sped 54 yards to the TCU 11, setting up a two-yard touchdown dive by John Walker.
Craig Curry tipped a third quarter pass that Cade caught and returned 16 yards to the TCU 49, leading to Raul Allegre's 21-yard field goal. The Texas secondary also was called four times for pass interference.
Late in that quarter, Texas middle linebacker Doug Shankle threw Reuben Jones for a seven-yard loss, and Graham charged in from his safety position to recover Jones' fumble in the end zone.
After a 47-yard interference penalty set up Porter's third field goal, a 41-yarder, Texas drove 80 yards for its final score. Junior quarterback Robert Brewer, in his first college start, threw to tight end Mike Chapman for nine yards and a touchdown. It was Chapman's first college reception.
