UPDATE: Speight reportedly out with a broken collarbone

ANN ARBOR -- Michigan may or may not have a new starting quarterback Saturday against Indiana.

Michigan coach Jim Harbaugh said Monday that quarterback Wilton Speight could be a game-time decision this week, depending on how he feels.

Speight appeared to suffer a left shoulder injury during the Wolverines' second to last drive against Iowa on Saturday. He had it looked at on the sideline, before returning to the game after Channing Stribling's interception.

After the game, he spoke with the media -- without any ice or a shoulder sling -- and said he felt sore, but wouldn't know more until later in the week.

Harbaugh would not give specifics on Speight's injury Monday.

"It'll depend on how he feels," Harbaugh said.

Junior John O'Korn has been Michigan's primary backup this season, with classmate Shane Morris behind him at No. 3.

If Speight can't go, Michigan will likely turn to O'Korn.

And, at least early this week, those two will get plenty of work in practice.

"I would anticipate today, the next couple days that (O'Korn and Morris) will get the majority of the reps," Harbaugh added.

Speight finished the Iowa loss 11 of 26 for 103 yards and an interception, his worst day of the year.

For the season, Speight has thrown for 2,156 yards, 15 touchdowns and 4 interceptions with a 62.3 percent completion rate. Speight's 148.8 quarterback rating ranks third in the Big Ten.

In reserve duty, O'Korn is 13 of 18 for 114 yards and 2 touchdowns in eight appearances. He's also rushed 6 times for 12 yards.



Morris is 4 of 5 for 85 yards in 6 appearances this season.
