Michigan junior receiver Martavious Odoms will miss extended time after suffering a broken foot in Saturday's loss to Michigan State.
Wolverines coach Rich Rodriguez said Monday that he wasn't sure if Odoms' injury will be season-ending.
Odoms is tied for second on the team with 15 catches and has 214 receiving yards. He also has one punt return and one kickoff return.
Rodriguez also said starting center David Molk and starting defensive tackle Mike Martin sustained sprained ankles against Michigan State, although both were expected to be fine.
Michigan next faces Iowa on Saturday.
