Michigan's 42-17 win over Iowa didn't come without cost. The Wolverines appear to have lost their leading rusher, junior tailback Fitzgerald Toussaint, for the remainder of the season after a leg injury. 

Per mlive.com, Toussaint was taken to a local hospital and underwent surgery after suffering the injury in the first quarter and being stretchered off the field. Reporter Kyle Meinke wrote that Toussaint's season "is expected to be over."

Michigan coach Brady Hoke declined to issue any details on the injury, saying he needed to speak to Toussaint's mother first.

Toussaint ran for 1,041 yards in 2011 to emerge as the Wolverines' most consistent threat at running back but struggled with off-field issues in the offseason and injuries during the 2012 campaign. Though he remains Michigan's leading rusher from the tailback position in 2012, his season appears to be done after only 483 yards and with only a 3.8 yard-per-carry average.

Toussaint will be replaced by sophomore Thomas Rawls (who finished with 22 yards on eight carries vs. Iowa) and possibly senior Denard Robinson -- the quarterback who is the Wolverines' leading rusher with 946 yards -- who saw several snaps from tailback against the Hawkeyes and finished with 98 yards on 13 carries.
