Another fighter that has boarded the bus of speculation about a possible fight between Conor McGregor and Floyd Mayweather is UFC fighter and executioner of the Irishman, Nate Diaz.

The Mexican-American, unlike many others, said that McGregor has a chance of winning, as long as it is in the early rounds.

"I think it's a publicity stunt. But from my point of view, between the two, I think McGregor is good and has the possibility of making something happen in the first, second, or third round. If he does something, it would be in round two or three," Diaz said on a Comcast program.

"He has an amateur style, good movement, good punches for six or eight minutes, but he is very amateur for Mayweather. What I'm saying is that he has a chance to win with one punch," he pointed out.
