Freshman Will Johnson got the start at cornerback in place of Green.
Green was hit by a helmet during an altercation that occurred in the tunnel of Michigan Stadium after the Wolverines' win over Michigan State last weekend. A Spartans player swung his helmet at Green multiple times. According to Green's father, Green was hit in the face, the back and the shoulder and was being looked at for a concussion.
Despite having Green available for Saturday's game, the Wolverines were without starting left tackle Ryan Hayes, safety Makari Paige, receiver Roman Wilson and linebacker Jaylen Harrell, according to the Big Ten Network.
The Wolverines won 52-17.
