Jim Harbaugh didn’t want to go into specifics about the injury that Wilton Speight suffered on Saturday against Iowa.

The Michigan quarterback was in noticeable pain that appeared to be from a left-shoulder injury.

According to mgoblog.com, that injury was more serious than originally suggested. Speight will reportedly miss the rest of the 2016 regular season with a broken collar bone.

The team hasn’t confirmed Anbender’s report. In fact, Harbaugh said on Monday that Speight’s status for Saturday had not been determined yet.

If it is indeed a broken collar bone, the Wolverines would likely turn to John O’Korn, who has yet to start a game at Michigan after transferring from Houston. He would obviously be tasked with leading the Wolverines in a do-or-die game in Columbus in the regular-season finale.

Michigan has avoided the catastrophic injury all season. If Speight is out for the year, it would certainly be the biggest hurdle for the Wolverines to overcome in their path to the College Football Playoff.
