WEST LAFAYETTE, Ind. — Ohio State sophomore quarterback Terrelle Pryor committed four turnovers today, losing two fumbles and throwing two interceptions in the Buckeyes’ 26-18 loss at Purdue. In seven games, Pryor has thrown eight interceptions and fumbled nine times, losing four of them. He actually had two other fumbles today that Ohio State recovered. After one interception, when Pryor stepped up in the pocket and threw a deep ball toward freshman receiver Duron Carter that was intercepted, Pryor banged his helmet against the ground as he reached the sideline and seemed to say something in frustration to Carter. “It maybe wasn’t a perfect ball,” Pryor said. “I just thought he might have played a little defense and it down. It all comes on the quarterback.
