Michigan's quarterback is out for multiple weeks.
Jim Harbaugh provided an injury update to starting quarterback Wilton Speight today.
Michigan's QB is out "multiple weeks" according to the Wolverines' head coach.
Harbaugh did not divulge the injury, though it was sustained in the win over Purdue last week.
Some believe John O'Korn has earned the right to be the starting quarterback moving forward regardless of Speight's status.
O'Korn threw for 270 yards and 1 touchdown in the win over Purdue.
Michigan is set to play Michigan State on Saturday night.
