Terence Crawford raged at a member of Errol Spence’s camp as he launched into an X-rated rant during Thursday’s final press conference.
The unbeaten American stars come to blows this weekend in an undisputed match-up for all four world welterweight titles.
It is no secret that the pair share a bitter rivalry, with the fight five years in the making.
Known for his usual relaxed and composed persona, Crawford uncharacteristically lost his cool in the presser as he took aim at someone in the crowd.
The person in question angered Crawford by shouting at him while he was answering a question.
It led to the 35-year-old to repeatedly label the person as a ‘b****’ while continuously repeating the N-word.
Crawford could be heard saying, ‘you ain’t going to bring nothing’, while also asking the individual, ‘you a b****. Who the f*** you talking to?’
He also stated: “Real n****** don’t talk n*****, and you talking too much. You want some attention?”
‘Bud’ then took to the microphone later in the press conference, where he pleaded with both camps to calm down as tempers flared.
The WBO king remarked: “Listen, my family, Errol’s family, man you got to calm down brother, because listen, things can get real sticky, real quick.
“And then everybody will say, ‘this is what we do everytime that we come out’. Social media, social media, my a**.
“Bro, listen, just like you doing all that talking, it can turn deadly real quick, but on both sides. So why not support your fighter?
“Let’s come together and make this event a success instead of everybody saying that every time we get together, it’s always shooting and violence.
“That’s what I want, y’all can say whatever you want, but I’m probably older than you and have been through way more than you so I’m more mature.
“But I wish Errol and his people the best.”
