NORMAN, Okla. (AP) - Injuries are testing the offensive line depth for No. 13 Oklahoma.

After losing two starters before the season even began, the Sooners (7-2, 5-1 Big 12) have continued to get banged up over the course of the season. Center Gabe Ikard, who took over the spot whenever Ben Habern quit football over lingering injury concerns, missed Saturday's 42-34 win against Baylor because of a head injury and left tackle Lane Johnson was limited again with an ankle injury.

Freshman Ty Darlington made his first career start at center, and Oklahoma got a steady performance from its makeshift offensive line while compiling 460 yards, including 183 on the ground.
