Floyd “Money” Mayweather charged towards a fan of UFC Lightweight Champion Conor McGregor after the fan was heckling him.

On Wednesday, the final press conference took place for the upcoming boxing match between Mayweather and McGregor.

After the press conference, Mayweather was taking photos for the media. While on stage, someone started heckling him saying he was going to lose on Saturday.

After hearing the McGregor fan, Mayweather charged towards him, asked him his name, and told him to be at the fight on Saturday night.

“Saturday night, after the fight, you won’t be speaking the same words. Mark my word,” Mayweather said. “I’m going to remember you.”

Mayweather will be putting his perfect 49-0 boxing record on the line when he steps into the ring with McGregor. Mayweather has not competed in the sport since retiring almost two years ago.

Mayweather vs. McGregor will take place Aug. 26 at the T-Mobile Arena in Las Vegas.
