Dereck Chisora has sensationally threatened to pull out of his fight with Joseph Parker.
The heavyweights are due to clash in London on October 26.
But Chisora has demanded more money as the chief support to Josh Taylor’s unification clash with fellow light welterweight champion Regis Prograis.
The Scot will clash with his American rival in the final of the World Boxing Super Series with the winner taking home the Muhammad Ali trophy.
But a furious Chisora said: “Who's the main event of this fight? I'm not selling out the O2 to main event for these boys.
“No cares about the Muhammad Ali trophy. If I'm not going to main event I want more money or I'm pulling out the show.
“I feel like you are f***ing me with no Vaseline.”
Chisora knocked out in his last fight but has since split from trainer Dave Coldwell.
And turned the air blue as he ranted about playing second fiddle to Taylor and Prograis.
He then stormed out of the press conference while the main event fighters were addressing the media.
Prograis said to Chisora: "We're number one and number two in the division,” to which the heavyweight responded: “No one cares about you."
