Before the season, Michigan touted its depth on defense and now it is getting the opportunity to prove it. Against Iowa, the Wolverines suffered more injuries to key seniors on the defense in Dan Rumishek and Cato June. Here is a look at some of Michigan's injured players and their replacements.

Injured player: Julius Curry, punt returner Replacement: Markus Curry Juilus Curry was sorely missed on punt returns, where his brother could not muster the same steady play. When Michigan was down 10-9, Markus fumbled a punt return, which gave Iowa the momentum it needed to score 24 unanswered points.

Injured player: Adam Stenavich, left tackle Replacement: Courtney Morgan

Like Curry, Adam Stenavich's replacement, Courtney Morgan, did not perform quite as well. Morgan was part of an offensive line that allowed five sacks on the day. Morgan himself was victimized by Iowa's Harold Hodges, who notched three tackles for loss, two of which were sacks.

Injured player: Zia Combs, cornerback Replacement: Jeremy LeSueur

After it was announced that Zia Combs was done for the season, cornerback Jeremy LeSueur became his permanent replacement. While the mention of his name makes some Michigan fans cringe, LeSueur has played well in place of Combs. Against Iowa, LeSueur was the Wolverines' fourth-leading tackler with eight solo stops. This performance followed the career game LeSueur had against Purdue, when he led the team in tackles and defended two passes.
