The Buckeyes were leading 28-21 when Barrett carried on second and 1 at the Ohio State 33 with 14:45 left in the fourth quarter. He was on the field for 3 minutes before his right leg was put into a temporary air cast and he was lifted onto a cart.
Michigan quarterback Devin Gardner came to his side and spoke to him before he was taken off the field.
Cardale Jones replaced Barrett.
