Michigan surprised many observers when they announced they would have four captains this year.

As it turns out, they are going to open the season with just two.

Linebacker Jake Ryan is out until at least October as he recovers from a torn ACL, and Brady Hoke announced Monday that safety Courtney Avery is expected to miss two weeks after having arthroscopic knee surgery over the weekend. Avery found out that he had been named captain the day after his operation.
