This is the latest report from WWE.com:

UPDATE: WWE.com has learned that Cena's procedure was successful and that Dr. Joseph Maroon, renowned neurosurgeon, Professor of Neurosurgery at the University of Pittsburgh Medical Center and Team Neurosurgeon for the Pittsburgh Steelers, was very positive regarding Cena's condition.

“We performed a microsurgical removal of a large disk fragment compression on the spinal cord which was weakening the nerve leading to the right arm," Dr. Maroon told WWE.com shortly after the operation. "We created a small incision in the front of the neck using an operating microscope to remove the fragment from the spinal cord and nerve. The operation took approximately an hour and a half.

"I think John’s prognosis is excellent," he added. "We performed this same procedure on three all-pro NFL players; and all three resumed their football careers.”

Please check back later with WWE.COM as we plan another interview with Dr. Maroon following John Cena’s post-surgical recovery treatment.

Cena's injury was the horrific outcome of a high impact Batista Bomb that caught an airborne Cena off the top rope at SummerSlam, resulting in numbness in his right arm and extensive pain in his shoulder. (Watch footage of Cena's injury at SummerSlam)

“You can either do one of two things: be upset or know what you can do to get better,” said former WWE Champion Cena prior to the surgery. “The ultimate goal is to be as strong as I can and get back into the ring as soon as possible.”
