Dereck Chisora has said he will walk away from his heavyweight fight with Joseph Parker next month if it does not top the bill.
The 35-year-old made the threat at an explosive press conference previewing the October 26 bout at the O2 Arena in London.
The fight is currently on the under card to the final of the World Boxing Super Series between super-lightweights Josh Taylor and Regis Prograis.
But Chisora, who produced a string of expletives to make his point, is demanding a move up the running order.
"Give me main event or pull me out of the show," he said at his press conference, according to the BBC. "I'm not going to sell out the O2 for them guys to be the main event.
"I'm being serious, you want me to sell it out to the London crowd, my London fans, then put these little guys that no one knows about on my show and mug me off.
"I'm taking the main stage, if not I want more money."
American Prograis tried to interrupt to remind Chisora that his fight was the main event, but the Briton was having none of it.
"Don't get me started," he said. "No one cares about you.
"I'm tired of selling shows and not making money so give me some of the money you are making. Boxing is thriving with the heavyweights, the big guys in the top 10.
"Let them box in Glasgow and they can sell it out there."
