EXCERPT FROM WWE.COM:
The Rated-R Superstar had been suffering numbness and uncontrollable trembling in his arms and hands. This is not the first time Edge has experienced these symptoms of nueropraxia. An MRI in Atlanta last Monday was sent to Dr. Joseph Maroon, a renowned neurosurgeon and professor of neurosurgery at The Pittsburgh School of Medicine. After careful examination of the MRI, it was determined that Edge would never be cleared to compete again, and thus, he is forced to retire.
Man, this SUCKS. Edge has always been one of my absolute favorites and a total delight to watch perform. There are a ton of feuds I was really looking forward to seeing, for instance Miz vs Edge, a heel Christian vs Edge, and well I could go on and on.
Still, there's something great to be said about this. In three weeks, he would have wrestled a ladder match. A regular match in its own right is dangerous enough but a ladder match magnifies that so much more. Guaranteed, if this injury is as bad as it seemingly is, that ladder match would have done horrors to Edge's health. Above and beyond anything else, I think all of the true fans have an appreciation for these guys to the point where it doesn't matter if we get to see that one last match in comparison to making sure they stay healthy. Edge has put on so many classic matches and entertained us for so many years that he doesn't owe us anything and NEEDS to take his health as top priority. I'm very, very glad that they were able to catch this ahead of time so we don't see what the results would have been at Extreme Rules.
Edge retiring from WWE leaves a gaping hole in the roster because of just how important and good he really was. It's been a tough year for WWE and this is a MASSIVE blow, to lose one of their best performers.
As the people were chanting in the arena: thank you, Adam Copeland, for entertaining the hell out of us for so long. We'll see you in the Hall of Fame soon, no doubt.
