Wilton Speight participated in some warmups for No. 4 Michigan before it faced Indiana.

The right-handed Speight hurt his left shoulder in last week's loss at Iowa. Harbaugh refused to say, at late as Thursday, if Speight would be cleared to play the Hoosiers.
Speight threw passes with the rest of the Wolverines' quarterbacks before Saturday's game, but did not take snaps. When Michigan's first-string offense ran its first play in warmups, O'Korn took the snap and handed off to De'Veon Smith.
It appeared as if Jim Harbaugh was getting John O'Korn ready to make his first start for the team, and to keep rival and second-ranked Ohio State wondering if it should prepare to play against Speight next week.
Korn seemed to hint he was going to get a shot to play when he posted a picture of him and the words, "Let's ride," on Instagram on Friday night.
