NORMAN — Oklahoma quarterback Baker Mayfield passed concussion tests given to him both during Saturday's win over TCU and Sunday, and his removal from the game after halftime was precautionary, according to sources close to the program.

OU medical staff will continue to monitor Mayfield's status over the next couple days, but the signs so far appear good for Mayfield's chances to play in next weekend's season finale at Oklahoma State, where the Sooners can secure the Big 12 championship.

And given the Sooners' struggles offensively after halftime Saturday, Mayfield's status for Bedlam could easily be the difference between winning and losing.

Indeed, Mayfield has become absolutely indispensable this season. His gutsy performance in the second half at Tennessee two months ago allowed the Sooners to rally and score a major victory in a tough environment.
