On Monday’s Raw, John Cena revealed he is suffering from a torn triceps.

"I cannot put off my surgery any longer. Tonight I leave the WWE," Cena said while praising Daniel Bryan for beating him fairly and squarely at SummerSlam.

"John has been dealing with a large left elbow bursitis,” said WWE's Dr. Michael Sampson. "We did an MRI which showed a partial triceps tear. Being the warrior that he is, he did not want to have surgery [forcing him to cancel his SummerSlam match].”

"After SummerSlam, John agreed with us to have surgery this week with WWE's Dr. James Andrews. He will begin physical therapy after that.”

Cena is expected to be out of action for four to six months.
