Tyson Fury and Deontay Wilder had to be separated by security during a heated and lengthy stand-off before the final press conference.
The presser in Las Vegas was delayed by a full five minutes as security and team members tried to pull the heavyweights away from each other.
Wilder was waiting for Fury when he was invited to make his entrance and the pair immediately went nose-to-nose at the centre of the stage.
With no security in sight, the exchange quickly escalated before the Gypsy King shoved his rival after receiving a push from the Bronze Bomber. When calm was eventually restored and the fighters were convinced to sit down, Wilder opened with an angry statement rebuking Fury’s claim he had made the WBC champion a star.
‘This is the final countdown and well should be happy,’ he said.
‘This is what we’ve been waiting for. ‘The biggest fight of both our lives.
‘I’ve been waiting so long to put my hands on a body, but someone put on their running shoes.’
‘Don’t you ever forget who brought you back to big time boxing,’ Wilder said directly to Fury.
‘The fans are here to see me do unfinished business.’
Fury, who kept his hood up and dark shades on through-out the presser, responded: ‘Wilder is spouting rubbish.
‘I gave him his biggest payday and brought him to Vegas.
‘And this is how he thanks me? I’ve fed him, looked after him, he owes me.’
Insults continued to fly between the two men, even when the broadcast cut to commercials.
The tension was eased by the introduction of each fighter’s trainer on stage and the press conference ended without any further fireworks, or the customary final face-off.
Fury and Wilder go to war again on Saturday night, with the winner expected to proclaim himself the best heavyweight in the division.
