Manningham out?

My sources in Ann Arbor have told me that there is a good chance that Mario Manningham will miss this Saturday's game against Penn State. If you recall, Manningham caught the game winning pass in the closing seconds of last year's Penn State-Michigan game. If this is true it will be a big blow to the Wolverine receiving unit as they will need Steve Breaston to step up his play. Michael Hart also has an injured ankle but is expected to play this week.
