Big 12's top teams battling injuries

Oklahoma and Oklahoma State are in the top 5 and undefeated, but both may be tested by limited personnel soon.

Oklahoma center Ben Habern suffered a broken radius bone and underwent surgery on Sunday. He's expected to be out at least a month before he may return at guard, in hopes of being able to snap the ball a few weeks later.

Oklahoma State lost starting right guard Jonathan Rush for the season with a left knee injury, and cornerback Devin Hedgepeth will miss the remainder of the season with a ruptured Achilles tendon.
