Quarterback Arch Manning sustained a concussion on the first play in overtime during No. 22 Texas’ 45-38 victory over Mississippi State on Saturday, ESPN reported.

Manning’s helmet appeared to bounce off the field following a hit from defensive lineman Kedrick Bingley-Jones at the conclusion of a 13-yard scramble play.

Manning sat on the field while trainers rushed out on the field. He was in the medical tent at the end of the game.

“We’ll find out more when we get back to Austin,” Longhorns coach Steve Sarkisian told reporters of Manning.

Troy transfer Matthew Caldwell tossed a 10-yard touchdown to Emmett Mosley V for Texas (6-2, 3-1 Southeastern Conference), which rallied from a 17-point deficit in the fourth quarter against the Bulldogs.

Manning completed 29 of 46 passes for a career-high 346 yards and three touchdowns. He also rushed for a score for the Longhorns, who host No. 10 Vanderbilt (7-1, 3-1) on Saturday.

“I thought Arch battled his tail off.” Sarkisian said. “I wish we played a little better around him at times … but man, he’s a warrior and he battles. He competes, he takes hits and he gets back up … I think he grew up a lot tonight.”
