Michigan defeated Rutgers 52-0 this past weekend and in the week ahead, will have to host No. 14 Iowa.

The Wolverines, however, won’t be at 100 percent:

McCaffrey suffered a concussion in the team’s 35-14 loss to Wisconsin two weeks ago and was splitting snaps with quarterback Shea Patterson this season. Being listed as doubtful means that he is closer to not playing than he is playing, which can certainly change what Michigan wants to do offensively at times.

Along with McCaffrey, linebacker Josh Ross is doubtful as well, as he suffered a high ankle sprain against the Badgers. Ross was in a boot on the sideline while the Wolverines crushed Rutgers.
