Michigan quarterback Wilton Speight will be out "multiple weeks," per head coach Jim Harbaugh and fifth-year senior John O'Korn will start Saturday against Michigan State.
Harbaugh did not offer specifics with regard to Speight's injury, only saying he'd be out this week and for the foreseeable future.
"He won't be able to compete this week or for multiple weeks (due to injury)," Harbaugh said. "He's going to be out. John O'Korn will be the starter."
Speight left Michigan's road game at Purdue two weeks ago after taking a hit to the back of the head and neck area.
