Heavyweight contender Derek Chisora is ready to go through fire in order to secure a big win over former undisputed cruiserweight champion Oleksandr Usyk.
Chisora will look to derail Usyk's heavyweight run on Saturday night, when they collide at the SSE Arena in Wembley.
Usyk made his heavyweight debut last year, but he wasn't exactly spectacular with his stoppage win of late replacement Chazz Witherspoon.
At heavyweight, Usyk was physically bigger. He was not the rapid fast fighter that many saw at 200-pounds.
Usyk is currently the WBO's mandatory challenger to unified world champion Anthony Joshua.
Should Usyk win, he plans to force a mandatory fight with Joshua, who first has to beat the IBF's top challenger Kubrat Pulev on December 12.
But Chisora has the same idea. He wants to knock off Usyk in order to secure a direct line to a fight with Joshua.
To get the job done, Chisora plans to make it a very physically fight from the opening bell.
"He has to fight my fight, that's all I can say,"Chisora told Sky Sports. "I can't fight his fight, I'm going to bring him down to the trenches.
"Yes, I'm going to eat some leather, but I can guarantee you, when I land my leather, he would know. I'm prepared to eat leather, 100 percent. Is he prepared to eat my leather as well? I don't think so. I'm ready to eat all he's got.
"I'm cranking up the heat from round one to whenever the fight stops."
