WACO, Texas — Baylor quarterback Bryce Petty has two cracked small bones in his back.
Petty had an MRI exam Monday, a day after taking an early shot to his back and playing only the first half of the 10th-ranked Bears' season-opening 45-0 win over SMU.
The diagnosis was two cracked transverse processes, small bones that stick out from each side of a vertebra.
Petty was day to day, coach Art Briles said.
"I was battling through some stuff that whole first half," Petty said after the game. "I couldn't really plant and throw as well as I wanted to."
