Baylor quarterback Bryce Petty had an MRI on Monday that revealed the extent of the back injury he suffered on Sunday in the team's season opener.

Petty is day-to-day with two cracks in the transfer processes of his back, CBS Sports reports.

A team spokesman said the MRI showed that bones sticking out from Petty's spine were cracked. On Monday morning, Petty said he expects to play Saturday against Northwestern State.

"I'm bummed out because it's never fun being hurt," Petty said. "Bummed out because I just watched the tape and everything is off. You never want to make any excuses. When you're throwing and I can't torque [it's frustrating]. Every time I went to throw it would jolt. It felt like somebody was punching me in my side."

The reigning Big 12 Offensive Player of the Year said he was hit from behind in the lower back by a face-mask on the opening series of the Bears' 45-0 rout with SMU on Sunday.

"Right now, [I] can't sit down right, can't walk right," Petty said.

Monday is a day off for Baylor. Petty is expected to test out his back on Tuesday. He claims he is treating the injury with ice and "non-invasive methods".
