DETROIT – Michigan football will be without their starting quarterback Wilton Speight for multiple weeks, according to coach Jim Harbaugh.
Backup quarterback John O'Korn will fill in as starter, including for this weekend's rivalry game against Michigan State in Ann Arbor.
O'Korn took over for Speight following an injury against Purdue in September, a game Michigan won.
Michigan will face Michigan State on Saturday night at the Big House. Michigan enters the game with a 4-0 record, while the Spartans are 3-1.
