We don't know why, when, what weight or against who, but CM Punk sure will fight in the UFC.

The why (money), when (mid 2015), weight (185 pounds), where (Chicago, Illinois) can all sort of be deduced, but who the former WWE superstar will face in the Octagon is a much more interesting question.

UFC fighters in nearly every weight class have gone to work calling out the 36-year-old pro wrestler on Twitter, but they're wasting their breath.

According to UFC president Dana White, Punk's future opponent likely doesn't even have a Wikipedia page at the moment.

"[CM Punk] wanted to fight here," White told ESPN.com. "He wanted to give it a shot, so we gave him an opportunity. It's not like Brock Lesnar. We're not going to throw the kitchen sink at him. Lesnar had a wrestling background. [CM Punk] is going to fight a guy who is 1-0, 1-1, 2-1 -- something like that."

Paying to watch a fight between two men with a combined record of 1-0. Sounds like a plan.

FANPOST OF THE DAY

Today's Fanpost of the Day comes via neonfish.

CM Punk - It's clobbering time

First off, I have to admit that I've been a Wwe fan growing up in the 90s and watched some of it ‘on and off' for the last few years. One of the storylines that kept me hooked was witnessing the ascension of CM Punk from Ring Of Honor almost a decade ago to the big leagues of professional wrestling. Here was a guy that nobody thought was going to make it to the Wwe let alone be one of their major players and yet against all odds and conventional business sense CM Punk rose up the ranks to reach the proverbial mountain top and finally get his due under the bright lights of the entertainment circus managed by Vince McMahon. ...
