COLUMBUS, Ohio (AP) — Ohio State quarterback Braxton Miller has a sprained left knee and will be evaluated at halftime, coach Urban Meyer said.
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 its third touchdown, he jogged across the field to the Ohio State bench.
Meyer, speaking at halftime with the third-ranked Buckeyes ahead 35-0, said Miller had a knee sprain and would be evaluated to see if he could play in the second half.
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.
A team doctor manipulated his left knee at one point and he grimaced in pain. Miller was then taken by motorized cart to 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, ran for one and handed off to Jordan Hall and Dontre Wilson for scores.
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.
