Conor McGregor has revealed that a disqualification against Floyd Mayweather during the pair's fight in August would have cost him $10 million.
In the run-up to the fight, fans and pundits were rabid with predictions and many considered the possibility the two-weight UFC champion might, whether by accident or design, slip into Mixed Martial Arts and make an illegal move against 'Money' Mayweather.
And it turns out they weren't the only ones as it was written in as a stipulation of the encounter by Team Mayweather.
As part of his preparation for the Dubliner's first foray into the professional boxing, McGregor hired experienced referee Joe Cortez to supervise his sparring sessions.
Although McGregor lost to Mayweather via 10th round stoppage, he kept within the Marquis of Queensbury's rules. The closest he came to MMA style fighting where a few light blows to Mayweather's head from within a clinch late in the fight when the UFC star was beginning to tire.
Speaking recently in Glasgow, McGregor admitted he got the sense Mayweather's camp didn't think he would take it seriously.
"Here's when I knew I was up against it: The ref was like, even if I lift my leg up, it's a point deduction. I'm like, "How is that a point deduction without even a warning?" he said, as per the Daily Mail.
"So they're telling me they're going to deduct points straight off the bat. And if I do get disqualified for any reason, it was a $10million fine. Ten million f***ing dollars.
"They were making up all these f***ing stipulations like I wasn't taking it seriously. Like I didn't have a hall-of-fame referee at my camp present at every single spar. Do you know what I mean?
"I had a boxing referee in Ireland, a great boxing referee in Ireland and then Joe Cortez in Vegas, every single spar. I put in so much work and had given so much respect to the rule set and the discipline, I was kind of expecting it back.'
There's plenty of speculation regarding what McGregor will do now. His payday against Mayweather far surpasses any purse he is likely to win in the UFC. Whatever his next fight, at least in financial terms, will likely be a step backward. Nevertheless, it would appear the 28-year-old is eager to defend his lightweight title.
He added: "Look, I've got the UFC title to defend and that means something to me. I will defend that world title.
"Nathan (Nate Diaz) is there. He's trying to come in here and make all of these demands. If he starts pricing himself out of an event, I probably will defend against the person who wins this interim belt... or someone along that line to legitimise it again.
"I've already gone from the highest of the high in terms of a money fight. Now the question I always get is about defending the belt and legitimising the sport and the rankings."
