After limping off the field against Indiana the week before, Michigan running back Blake Corum wasn’t available for the Wolverines Saturday showdown with Penn State.

Without him, Michigan still managed the 21-17 victory over the Nittany Lions.

The ABC broadcast of Saturday’s game indicated Corum would be out for two weeks, but Wolverines head coach Jim Harbaugh was less committal about a timeline.

The Michigan running attack was led by Hassan Haskins in Corum’s absence. Haskins racked up 156 yards on 31 carries on the day. The win was the ninth of the season for Michigan and keeps them in the mix for the division title in the B1G East.

So far on the season, Corum has run for 778 yards on 130 carries and found the end zone 10 times. He also has 20 catches for 137 yards and one receiving touchdown.

The No. 8 Wolverines head to Maryland on Saturday, Nov. 20, but with No. 5 Ohio State coming to Ann Arbor the following week, a healthy Corum on the field will be key if Michigan hopes to send the Buckeyes home with a loss.
