Is LewJack hurt?

How hurt is lewjack? They talked about his back but is his foot bothering him again? He seemed extremely slow on Saturday vs Michigan St. Maybe it was the travel mess that they went through, but he seemed really off. He could not get around his guy and the D wasn't very good either, which typically is a sign that he's not healthy. I hope that if he is banged up, that they rest him for a game or too. Give GDB and TJ some opps at the point. This Michigan game coming up is a big deal...this could be the make or brake for the tourney if they continue to struggle down the final month.
