Joel Klatt spoke about what he believes Michigan’s biggest concern is heading into its biggest game of the season against Ohio State.

Klatt believes that injuries are the biggest factor in Saturday’s game, specifically Blake Corum.

“The biggest question coming out of last week is going to be Blake Corum’s health,” Klatt said. “And quite frankly, that’s probably the question in the game. This whole week it’s going to be, ‘How healthy is Blake Corum?’ This is the cloud over the game right now.”

Corum went down in Saturday’s game against Illinois with a knee injury and his status remains unknown. Corum has been the focal point of the Michigan offense this season, racking up over 1,400 yards and 18 touchdowns.

Michigan struggled without Corum, almost losing to Illinois, but managed to squeeze out a win. That being said, the Wolverines will be severely depleted without Corum or Donovan Edwards who did not play at all against Illinois.

Klatt said that Ohio State fans won’t feel sympathy for Michigan, as the Buckeyes have been plagued with injuries too. Jaxon Smith-Njigba has wrestled with a hamstring injury for much of the year while the Buckeyes are also banged up in the backfield with TreVeyon Henderson and Miyan Williams battling ailments.
