Michigan’s defense was reeling against Notre Dame. Then it appeared to lose one of its most valuable players.
Devin Bush Jr., a preseason All-American at middle linebacker, was injured late in the second quarter, when a Notre Dame offensive lineman landed on his right leg.
When Michigan’s medical staff went out to treat Bush, he could be seen reacting in pain when they appeared to touch his right calf, according to the NBC broadcast.
Bush attempted to walk off the field, but eventually needed help. He was taken immediately to the locker room by the training staff.
Michigan radio said Bush was evaluated for cramps.
