The good news here is no Carlos Brown. Michigan's leading rusher missed practice Wednesday with an undisclosed injury, but he doesn't appear on the injury report. Mgoblog reported earlier today that Brown sustained a head injury during practice this week and is very doubtful for the game, so we'll see if he plays against Iowa. Senior running back Brandon Minor is getting healthier and could take on a greater carries load if Brown can't go. Brown leads Michigan with 336 rush yards and three touchdowns on 44 carries (7.6 yards per carry), while Minor has rushed for 179 yards and two touchdowns on 35 carries (5.1 ypc).
Wolverines linebacker Stevie Brown, offensive lineman Tim McAvoy, offensive lineman David Moosman and defensive end Tim North will serve as game captains.
