Michigan's quarterback dynamic is looking awfully thin, as head coach Jim Harbaugh announced Monday that Brandon Peters has been placed in concussion protocol, according to Dan Murphy of ESPN.
Peters took a big hit from Wisconsin's Andrew Van Ginkel during Saturday's eventual 24-10 loss, and needed to be carted to the locker room before being taken to hospital.
Prior to being injured, Peters had completed 9-of-18 passes for 157 yards. John O'Korn came in to replace the sophomore, completing just 2-of-8 passes for 19 yards the rest of the way.
Harbaugh did not say who the starting quarterback will be for the Wolverines' regular-season finale against Ohio State, and was not willing to say if injured senior Wilton Speight will be cleared for contact during practice this week, according to Murphy.
