Michigan coach Jim Harbaugh doesn’t know who will start at QB vs. Ohio State

Michigan coach Jim Harbaugh does not know who will start at quarterback against Ohio State. However, he would not tell anyone if he knew.

Starting quarterback Wilton Speight, who got injured in Michigan’s loss to Iowa, and backup John O’Korn took reps in practice on Tuesday.

"They both practiced," Harbaugh said on 97.1 The Ticket. "That was Tuesday, today's a new day. It was a good day for us yesterday. Our ball club had a very good Tuesday practice.

"We'll look to come back today and practice well again."

Amara Darboh, a senior wide receiver for the Wolverines, told reporters that Speight “seemed fine” during practice on Tuesday.

O’Korn started in last week’s 20-10 win over Indiana, but went just 7-of-16 for 59 yards. Speight has thrown for 2,156 yards, 15 touchdowns, and four interceptions in 10 games this season.
