WWE Hall of Famer Mick Foley has posted the following on Facebook, after a photo of CM Punk on a milk carton got a huge response online:

"Yes, the response to that funny photo of CM Punk on a milk carton was incredible. While I respect everybody's opinion – as long as it is given in a respectful way, I have to disagree with those out there who find great fault in Punk's simply walk away.

I am kind of like a ghost that drifts in and out of WWE, but in my past three years of drifting, I have never been to a WWE event where Punk was not in considerable pain. Ice packs, heating pads, and visits to the trainer were as much a part of his daily routine as eating. sleeping, and wrestling.

Performing at that level, in that degree of pain was only possible when accompanied by the passion that turned an unlikely Indy kid into one of the greatest WWE superstars of his generation.

Once that passion's gone, then so are all of the things that made him great. I know what it feels like to go through the motions, and to do what needs to be done solely for the paycheck. It's not pretty – and though I have not talked to Punk since the night before he left, I have to believe he has too much respect for what he does to let people see him going through the motions.

If or when that day comes when CM punk returns to WWE, I hope it's with that same passion that made so many of you care about him to begin with."
