PWInsider.com is reporting that the injury suffered by John Cena during last night’s Raw was legitimate. Cena stated on his official Twitter page that he would be undergoing an MRI today before the Smackdown taping in Grand Rapids. For those who didn’t see, Cena twisted his leg/ankle on his way out of the ring while chasing down Dolph Ziggler. Backstage segments featuring Cena went on as planned, but were shot live to note the injury.
