Dereck Chisora will go into Saturday's British and Commonwealth heavyweight title fight against Tyson Fury carrying the heaviest weight of his career. Zimbabwe-born Londoner Chisora weighed in at 261 pounds on Friday, 17 lb heavier than his last fight.
Fury claimed on BBC Radio 5 live that the winner is likely to face David Haye's conqueror Wladimir Klitschko.
Klitschko, who has twice pulled out of fights with Chisora, won a unanimous decision over Haye earlier this month.
"Wladimir Klitschko has shown a lot of interest in the winner of this fight. Unofficially this is a world title eliminator," he said.
"Hopefully the winner will do a better job than Haye, which won't be hard."
The unbeaten Fury's last outing was a fifth-round knockout of Marcelo Luiz Nascimento, while Chisora successfully defended his British and Commonwealth heavyweight title against Sam Sexton in September.
The pair share almost identical records with Fury collecting 10 knockouts compared to his opponent's nine en route to 14 unanswered victories.
But Londoner Chisora is confident he will dispatch the 24-year-old to place himself in Klitschko's sights for a third time.
"I will show everyone that I am the top domestic heavyweight and that Fury isn't what he thinks," he told the Barnet Press.
"Klitschko owes me a fight. I hope he's a man of integrity and honors his commitment to me."
