There wasn't much to worry about for No. 1 Ohio State or its fans during a 56-29 win over No. 13 Michigan on Saturday; the Buckeyes' eighth straight win over their most bitter rival. There was a moment during the third quarter, however, that led to hearts creeping into throats all over Ohio.

Buckeyes quarterback Justin Fields took a hit to his left knee after delivering a pass in the pocket. Fields immediately went to the turf clutching his knee, and athletic trainers came out to tend to him. After a couple of minutes, Fields was helped to his feet and walked off the field on his own.
