During his weekly Big 12 teleconference, Baylor head coach Matt Rhule said sophomore quarterback Charlie Brewer is under the concussion protocol.
Brewer is coming off the worst game of his collegiate career against West Virginia on Thursday, when he completed 1 of 8 passes for 22 yards and three interceptions.
It was the first time since playing for Baylor that Brewer threw more than one interception in a game.
Senior quarterback Jalan McClendon replaced Brewer for the rest of the game, completing 16 of 21 passes for 183 yards and no interceptions while rushing for one touchdown.
