According to the WWE website, Edge underwent an MRI last Monday.
After the MRI was examined by WWE's Medical Director Dr. Joseph Maroon, Edge was diagnosed with stenosis of the spine, which in layman's terms, means his spinal cord was narrowing from the abuse he's taken since returning to the ring from his 2003 neck fusion surgery.
With the damage to his spinal cord, continued abuse of the neck from bumping could result in series injury, including paralysis.
