Michigan football quarterback Cade McNamara began the second half of Saturday's game against Connecticut in the locker room with the Michigan training staff, according to the ABC TV broadcast.
It was not specified why he was being treated.
McNamara played the final series of the first half at Michigan Stadium and was greeted by a standing ovation from fans, just one week after they received flack for booing last year's starter and one of this year's captains.
On his first snap, he was dropped for a sack and a five-yard loss, but followed by completing an 18-yard pass to Ronnie Bell, his only pass of the game.
