Carey Murdock of SoonerScoop.com is reporting from the stadium that Gabe Ikard, the Sooners starting center, is not running with the first team in pregame warmups. According to Murdock, Ikard has reportedly been dealing with some concussion issues this week during practice and could potentially be held out of the Baylor game.

If true, it is a major blow to an Oklahoma offensive line that has little to no depth already. Admittedly, the Baylor defense should not present much of a challenge but this would leave true freshman Ty Darlington in Ikard's stead.
