6 WWE Superstars who quit wrestling too early

#4 CM Punk

CM Punk on WWE Backstage

CM Punk is one of the two most accomplished wrestlers on this list. He quit WWE one night after Royal Rumble 2014 and over six and a half years later, he's yet to return. He's stated no interest in it as well and has gone a long way since.

36 might not be a 'young' age per se, but when you look at the level that CM Punk competed in, it was clear that he had at least four or five more years left in him in terms of a main event run. He wasn't always utilized to his satisfaction but as we know, things in WWE can be cyclical. He made it no secret that he felt he deserved to be pushed consistently the way superstars like John Cena were and his career ended on bad terms after a string of frustrations with WWE and overall physical pain burned him out to the point of no return.

We feel he retired too young because there was still a lot more left for him to accomplish. However, we respect his decision to walk away and never come back. It's not often that we see that in WWE.
