NORMAN, Okla. — The Sooners suffered a major loss defensively, as defensive tackle Charles Walker will not play in the Texas game this weekend after suffering a concussion last weekend against TCU.

“We’ll also be without Charles Walker,” said head coach Bob Stoops. “I guess he said he got a concussion sometime in the game the other night. So he’ll be out.”

Walker, an NFL talent, was a force last weekend when he batted balls down on multiple occasions and wreaked havoc for the TCU offense.

He’s racked up seven tackles, including two for loss, and four pass deflections, plus two quarterback hurries in four games, so this is a huge hit to OU’s defense.

Walker also suffered a concussion leading up to the Orange Bowl against Clemson last year, so it's obviously more of a concern now, as it's a repeat injury.
