Dillian Whyte believes his domestic rival, Dereck Chisora, will see his career come to a close if the two boxers collide in a rematch.
Back in December of 2016, Whyte won a twelve round split decision over Chisora in a Fight of The Year candidate where both boxers went to war in every round of the contest.
Their mutual promoter, Eddie Hearn, has been banging the drum to match them in the ring for a second time.
And they have crossed paths and exchanged words several times - and the most recent confrontation took place during Friday's weigh-in for tomorrow night's fight between Anthony Joshua and Alexander Povetkin.
Chisora told Whyte that he'd pay him 5 million if a rematch was accepted.
"With Dereck Chisora you never know," Whyte told Sky Sports News. "He said he was going to write me a cheque for £5m to take the fight, so I said I'll sit and wait for the cheque to come. Please make sure it doesn't bounce. We'll see.
"I don't know where he's going to get £5m from, but let's see what happens."
Whyte is a frontrunner to face Joshua in April, at Wembley in London, should the heavyweight champion come away unscathed against Povtekin.
Chisora, who two months ago secured a sensational knockout victory over Carlos Takam at the O2 Arena, believes Whyte is afraid to accept the rematch because a loss would take away his high ranking with the sanctioning bodies.
Whyte views it in a different light. He believes a rematch would be the final nail in Chisora's career.
"Listen, I'm ready to go whenever," he said. "I want to put a key in that, and turn it, and throw it away forever. I believe if Dereck Chisora fights me it will be his last fight. The comeback king will be gone forever."
