CM Punk was backstage at UFC 218 over the weekend, something that may have gone unnoticed had it not been for Punk falling off of a chair.

UFC 218 took place in Detroit Michigan this past Saturday night. In the main event, Max Holloway defended his Featherweight Championship against Jose Aldo, although fair play to Aldo who stepped in to replace Frankie Edgar at just a month's notice. The card also featured wins for Francis Ngannou who defeated Alistair Overeem, and also Eddie Alvarez.

While there is a lot of crossover when it comes to fans of WWE and UFC, a lot of those fans who have a foot in both worlds are eagerly awaiting the news regarding whether CM Punk will fight inside the octagon again. The Straight Edge Superstar's first fight did not exactly go to plan as Punk lost to Mickey Gall mere seconds after the fight had begun.

Punk doesn't appear to have been completely deterred from the business however and was actually backstage at UFC 218 on Saturday night. The former WWE Champion was watching on as Paul Felder was interviewed backstage following his win second-round win over Charles Oliveira. No one would have known Punk was even there if it wasn't for a blunder on his part though. The Second City Saint fell off a chair off camera and Felder had to break from the discussion to address all the background noise as he jokingly shouted "straight edge my a**." Check out the incident below right at the beginning of the interview.

Although CM Punk is very clearly still invested in trying to make a name for himself in UFC, the rumors of him returning to pro wrestling are never-ending. Since his first foray into the octagon Punk has been told that Ring Of Honor's doors are always open to him, he reportedly turned down a $1,000,000 offer to wrestle in the UK, and apparently, even sources close to WWE say they would take Punk back in a heartbeat. With all that being said, he has recently had talks with Dana White—or is due to very soon—about the possibility of a second fight in UFC.

Why CM Punk left WWE and turned his back on pro wrestling is no secret, and if you believe Punk's side of the story then it's no surprise either. Despite losing resoundingly in his first outing in UFC, he still said he had no regrets and he loved every second of the time he was out there. Clearly, it hasn't deterred him either and if it's up to Punk we will see him fight in UFC again sometime soon.
