There's always plenty of tension at press conferences for the big UFC events as two fighters come face to face before they meet in the octagon. 

Most of the time, it only goes as far as an exchange of some trash talk, but yesterday at the press conference for UFC 178 and the fight between Jon 'Bones' Jones and Daniel Cromier, things got very heated and a proper scrap broke out.

Security were on hand to make sure things didn't go too far, but it still looked to be the real deal, rather than for show. Certainly, it will make the fight on September 27th that bit more interesting, but there was one man in attendance at the press conference who didn't seem all that bothered about it...Conor McGregor. In the video below (and main picture above), he can be seen posing with a fan for a selfie as the whole thing kicks off, and he seemed to enjoy how ridiculous it all was. 

While one of the best fighters in the game is engaged in a massive brawl with his next opponent on the floor, the fans still want more of Conor McGregor, confirming that he's serious box office, as if we needed further proof.

Speaking of McGregor, while we're at it you might as well check out his latest video feature, shot with Vice, who are profiling him as part of their Fightland series.
