Watch: Floyd Mayweather Calls Out Heckler At Final Press Conference Before McGregor Fight

Floyd Mayweather has no problem confronting boxing and MMA fans who think he’s overrated and will soon see his undefeated streak come to an end.

Floyd Mayweather vs. Conor McGregor fight news

During a press conference in Las Vegas on Wednesday — the final one before the 40-year-old boxing champion takes on Irish UFC star Conor McGregor at Sin City’s T-Mobile Arena on Saturday night — one heckler began harassing Mayweather (49-0), and the boxer had to step in and tell him to behave himself.

“He’s nervous!” the fan yells out.

“Listen, if you’re gonna be here, carry yourself in an orderly fashion, I told you that,” Mayweather responds, before McGregor joins in and suggests the heckler be kicked out and then says “This is Bruce Lee shit” and strikes a dramatic martial arts pose and carries on getting all up in his opponent’s face.

“Wouldn’t get too comfortable with that belt, Floyd!” the fan yells.

“Nah, can’t nobody beat me, my man,” the five-division world champion and 1996 Olympic bronze medallist retorts. “I don’t care where you’re from. If you’re with Conor McGregor, go over there. Can’t nobody beat me.”

“What happens on Saturday?” the heckler continues taunting.

Mayweather then asks a member of his team to hold his belt, approaches the fan and asks him his name, to which the heckler responds “Alex.”

“Alex, Saturday night after the fight I want you to come over, you’re gonna be speaking the same words,” warns Mayweather with an admonishing finger-point. “Mark my word.”

“Ok, I’ll be there, we’ll see,” the heckler responds.

The fight between Mayweather and McGregor is scheduled to begin at 9 pm EST on Saturday (Aug. 26) at T-Mobile Arena and will air on Showtime pay-per-view.
