No. 22 Michigan has issued its injury report for Saturday's game at Michigan State (Big Ten Network, noon ET).
Center David Molk, foot
Cornerback Zac Johnson, shoulder
Safety Mike Williams, ankle
Michigan's struggling secondary certainly could use Williams against the Spartans, so his progress bodes well. Williams has 16 tackles in three games and can aid in coverage as Michigan contends with a deep group of wide receivers and tight ends. Obviously, quarterback Tate Forcier's absence from the injury report indicates he should be fine for the game after hurting his shoulder last week. Running back Kevin Grady, defensive end Brandon Graham, running back Brandon Minor and left tackle Mark Ortmann will serve as game captains.
