John Cena injured?
From Zack Fisher:
John Cena was involved in a cage match with Wade Barrett at the live Raw show. Barrett hit his finisher on Cena and he looked to have landed awkwardly on his leg or his knee. Trainers ran out immediately for a few minutes. Wade walked around to give Cena some time and walked close and Cena put a submission on him. Barrett tapped out instantly to stop the match. John Cena then cut a promo after saying he might have to take time off. He clearly could not put any weight on his leg.
