CHAMPAIGN—Terrelle Pryor returned after an injury briefly knocked him from the game, then led No. 2 Ohio State on a clinching touchdown drive in the closing minutes in a 24-13 victory over Illinois on Saturday.Pryor ran for 104 yards and was 9 of 16 for 76 yards and two touchdowns through the air, but he gave Ohio State fans a scare when he needed help off the field early in the third quarter. The star quarterback spent a couple of minutes in the locker room before returning to the game.Illinois (2-2, 0-1 Big Ten) put a scare into the Buckeyes (5-0, 1-0) with under 5 minutes to go when it marched down field, but coach Ron Zook elected to kick a field goal on fourth down that made it 17-13, rather than go for the tying touchdown.The Buckeyes responded by going the length of the field for the clinching score.
