LSU this weekend will play a Texas team depleted at running back as freshman Jordan Whittington needs surgery to repair a sports hernia, coach Tom Herman announced Monday.

Whittington, who enrolled early as a five-star recruit, caught two passes for 17 yards in the Longhorns' 45-14 season-opening win over Louisiana Tech. Whittington limped off the field in the second quarter and did not return to the game.

Herman said Whittington tore "the abductor off his pubic symphysis" during his second reception, and he expects Whittington, who will have surgery in Philadelphia, to miss four-to-six weeks.

Whittington's injury depleted an already thin position. At running back, Texas now has sophomore Keaontay Ingram, converted freshman quarterback Roschon Johnson and freshman David Gbenda, who signed as a linebacker.

The Longhorns had five running backs entering the season, but senior Kirk Johnson and junior Daniel Young sustained injuries during preseason camp. Walk-on Jarrett Smith also has an undisclosed injury.

The position decimated by injuries, Texas moved Roschon Johnson to running back 10 days ago. It put Gbenda at running back for the first time Sunday night, six days before playing LSU.

Ingram rushed for 78 yards and a touchdown against Louisiana Tech. Roschon Johnson carried the ball seven times for 26 yards. Quarterback Sam Ehlinger is also a threat in the running game.

Despite having two running backs to face LSU, which held Georgia Southern to 98 total yards, Herman said Texas' general approach will not change.

"We're confident in Keaontay. We're confident in Roschon," Herman said. "Now, if something were to go awry in the middle of the game, then we'd have to change course."
