Filed under: News , UFC UFC featherweight champ Conor McGregor knows undefeated boxing great Floyd Mayweather will never fight him under MMA rules. “The Notorious” has said he’s willing to box Mayweather, but there’s no way UFC officials will ever allow that to happen. So why the hell does everyone keep talking about it? Well, for starters, neither McGregor (20-3 MMA, 8-1 UFC) nor Mayweather (49-0 Boxing) can stand to let pass an opportunity to fire off a verbal jab at one another. During a recent Facebook Live Q&A session with the U.K.’s The LADbible , the UFC featherweight champ was asked directly, “Will a fight between you and Floyd Mayweather ever happen?” While a simple, “No,” would have done the trick, McGregor did what McGregor does and seized the moment to add a little more fuel to the fire between these two unlikely rivals. Floyd Mayweather “Floyd’s afraid of a fight,” McGregor said.
