Conor McGregor has threatened to break WWE Legend Paul Heyman's jaw in a late night social media post.
Commenting on the news of the imminent sale of WWE to the Endeavor group - which also owns the UFC - McGregor posted a photoshopped image of himself holding both UFC and WWE title belts.
Heyman, who is the manager of WWE Undisputed Champion Roman Reigns, claimed that McGregor was just a 'Roman Reigns wannabe.'

The Notorious didn't take too kindly to this and threatened to break the legendary professional wrestling figure's jaw in three places.
"Careful Grampa. I'll show up and break your jaw in 3 places," wrote the Irishman.
Heyman has yet to respond to McGregor.
However, the founder of the famous ECW promotion had a busy night of his own as Reigns retained his titles at Wrestlemania against 'The American Nightmare' Cody Rhodes.
McGregor has long been rumoured to be interested in having a run in WWE, and now that UFC and WWE are under the same banner, perhaps an appearance isn't as far fetched as it may seem.
For now though, McGregor has enough on his plate with his upcoming bout with Michael Chandler in the coming months.
