Texas fullback Antwan Cobb is out for the season after suffering a knee injury late against Iowa State.
Cobb, a former Pflugerville High standout, sprained his left anterior cruciate ligament. He was being used as a tailback at the time of his injury.
With Cobb out for the year, the Longhorns now don’t have a true fullback, although it’s not a position they use much. Luke Tiemann, the only other fullback, still is out for another week with a bad wrist.
Texas coach Mack Brown said Monday that Chris Ogbonnaya, the second-team tailback, will move to fullback. Freshman tight end Blaine Irby also could see some snaps at fullback. He started practicing there last week.
Cobb also played on special teams. He scored a touchdown on a 16-yard pass against Arkansas State, his first collegiate play. In all, he had eight carries for 34 yards.
