(AP) Ohio State quarterback Braxton Miller has returned to the sideline after having his left knee looked at in the locker room.
Miller left the third-ranked Buckeyes' game against San Diego State after being pinned between tacklers.
He was taken to the locker room on a cart while grim-faced Buckeyes fans looked on. But shortly before the end of the first quarter, in the lull after Ohio State had scored to take a 21-0 lead, he jogged across the field to the Ohio State bench.
Miller, a junior tabbed as one of the top contenders for the Heisman Trophy, carried on fourth-and-1 at the Aztecs 12 on Ohio State's seventh offensive play of the game. He cut inside right end and was hit by defensive back King Holder and middle linebacker Jake Fely, Miller's helmet popping off as he fell.
He lay on the field on his back for a moment, holding his head. He then was helped to his feet and walked under his own power to the sideline with a slight limp before getting on the motorized cart and heading for the locker room.
With Kenny Guiton taking his place, the Buckeyes scored on the next play for a 7-0 lead.
Guiton also threw a touchdown pass and handed off to Jordan Hall for another. Freshman Dontre Wilson had opened the scoring on a 7-yard run on the play after Miller left the game.
Guiton, a senior, had taken over for an injured Miller late in last season's game against Purdue. He led the Buckeyes to an improbable touchdown and then threw a 2-point conversion pass to force overtime. The Buckeyes won 29-22 on the way to a 12-0 season.
