CM Punk has done with Wrestling as a whole. He will not be back with WWE nor any other promotions until he is out on the streets and comes begging back.
There are 2 sides to every story and, although i can understand the management wanting to keep a popular star on TV and at house shows, i cant see them putting his health and life at risk. I only say this as the WWE in the past wouldn't have cared but because of the latest round to debates about concussions and pain killer use i think they would be walking on eggshells.
