Mexican luchador Sin Cara was involved in a backstage pull-apart brawl with none other than Sheamus, during WWE's recent New York TV taping.
It is understood that the brawl took place backstage at a Smackdown taping, with Cara - who gives up around 80 pounds in weight to the Irish grappler - getting the better of the exchange.
Details are scarce at present, but it's unclear whether WWE will look to capitalise on the real-life heat for a future storyline, or swiftly sweep it under the rug.
United States champion Sheamus has moved quickly to deny the fight happening on Twitter, by posting: "Must be getting punchy. Don't remember being beaten up by Sin Cara backstage... It's just how Mexicans & we Irishmen hug it out fella ;)".
The former WWE champion is known to be a close friend and training buddy of Paul 'HHH' Levesque, which is a potential red flag for Sin Cara, formerly Hunico, and his future TV career.
This is not the first time Sheamus has been involved in a backstage scrap with a fellow employee, following reports several years ago about an incident involving Yoshi Tatsu.
The story goes that Tatsu, Sheamus and Ted DiBiase were room-mates whilst training for their respective WWE careers, and the much smaller Tatsu gave Sheamus a pasting.
For an ex-bodyguard and bouncer, the Celtic Warrior doesn't seem to be as legitimately hard as he thinks he is, judging by how handily he has been disposed of by two pint-sized wrestlers.
