Ohio State quarterback Braxton Miller was taken to the Wexner Medical Center on The Ohio State University campus, because of concerns of a possible concussion.
He was hurt late in the third quarter of the seventh-ranked Buckeyes' game on Saturday against Purdue.
OSU officials said that Miller was examined for head, shoulders, and neck injuries and cleared of all ailments.
He was released from the hospital, and is doing fine.
Miller, mentioned among the top Heisman Trophy contenders, was completing a 37-yard run when he was thrown to the turf by cornerback Josh Johnson.
Miller didn't get up for several minutes - he was in obvious pain - while he was attended by several doctors and trainers. Eventually he sat up.
Miller completed 9 of 20 passes for 113 yards with an interception and ran for 47 yards on 12 carries before leaving the game.
