Michigan QB Wilton Speight not expected to play Saturday

— -- ANN ARBOR, Mich. -- Michigan?quarterback Wilton Speight is not expected to play for the Wolverines this Saturday, multiples sources have confirmed to ESPN.

Speight appeared to injure his non-throwing shoulder in this past weekend's loss to Iowa. According to a report from Mgoblog.com, the redshirt sophomore quarterback broke his collarbone.?Head coach Jim Harbaugh said Monday afternoon that Speight "could be" a game-time decision for No. 3 MIchigan's game against Indiana this weekend.

Harbaugh did say that he expected back-up quarterbacks John O'Korn and Shane Morris to take the majority of the team's snaps during the first couple days of practice this week.

"That's good for them," Harbaugh said, later adding that "they've both had extensive practice time during the course of the year."

O'Korn has played in more than half of Michigan's games in a back-up role so far this season. He has completed 13 of his 18 passes for 114 yards and two touchdowns in relief of Speight. The redshirt junior transferred to Michigan after two years at Houston. He started for the Cougars as a freshman and part of his sophomore season.

Teammates said Monday that O'Korn may use his legs a bit more frequently than the 6-foot-6 Speight, but other than that there aren't many differences between the two quarterbacks and how they like to operate an offense.

Speight started the first 10 games of the season for Michigan, throwing for 2,156 yards and 15 touchdowns. He favored his left side during the fourth quarter at Iowa this weekend and finished that game with 103 passing yards, his second-lowest total of the season.
