Blake Corum shared some good news with the Wolverine faithful on Thursday in an interview with the Associated Press.

The Michigan running back said his surgically repaired left knee has gotten strong enough that he’s been cleared to run on an anti-gravity treadmill. Corum also stated that he is “100% sure” he will play in Michigan’s season-opening game on Sept. 2 against East Carolina.

Corum late last season tore his meniscus and sprained a ligament in his left knee against Illinois on Nov. 19. Corum only played minimally against Ohio State during the regular season, and did not play at all in the B1G Championship. Likewise, the running back remained on the sidelines as the Wolverines were defeated 51-45 in the CFP semifinals.

After his injury, Corum decided to forego the NFL Draft, and return to Michigan for another year. It’s a significant advantage for the Wolverines, as Corum posted 1,463 rushing yards and 18 touchdowns prior to his injury. The running back has been a mainstay for the Wolverine offense the past few seasons.
