WACO, Texas -- Baylor coach Art Briles said freshman quarterback Jarrett Stidham will be fine and will start this week against Oklahoma State after injuring his back in the Bears' 44-34 loss to Oklahoma.

Stidham played through the back injury, which he suffered in the first quarter of his second career start, and said he's dealing with "deep bruising." He underwent an MRI on Sunday, and the results were negative.

"We're just dealing with muscles and bruising, which equates to soreness and pain," Briles said. "No structural damage. That's the encouraging part. That's a good sign."

Stidham was 16-of-27 for 257 yards, two touchdowns and two interceptions in the loss. He said Monday he's feeling better and never considered exiting the game despite his back pain.

"I tried to not let it affect me at all," Stidham said. "In a big game like that, everybody is dinged up and we always talk about managing distractions. That was a distraction, and I can't let a little injury like that faze me in the biggest game of the year up to this point."
