Tyson Fury is to stage a 'fight' behind closed doors next month to assist preparations for his July showdown with Dereck Chisora.
Fury was due to appear at the Copper Box on 12 April in the second outing of a three-fight contract that concludes in the WBO final eliminator against Chisora, but that date has been pulled.
Mindful of the inactivity that has resulted from David Haye withdrawing from a proposed clash last month - Fury has now fought just twice in 15 months - the 25-year-old's camp have taken special measures.
Cameroonian Carlos Takam will be flown over for a full-on 12-round sparring session behind closed doors to bridge the gap between now and 26 July when he meets Chisora in Manchester.
"I will not be inactive or waiting around for anyone, dancing to other people's fiddle. It's all about me. You have to be selfish in boxing," he said.
"They want me not to fight and go off the rails, putting weight on and not train properly"
"I'm very disappointed that I won't be fighting on April 12. I'm not allowed to fight in that and not allowed to have an six or eight rounder anywhere else.
"It's about trying keep me inactive. They want me not to fight and go off the rails, putting weight on and not train properly. I'm ready to fight now and it's sickening that I can't fight.
"I'm still being paid whether I fight or don't, but I'd rather be fighting and they need every edge they can get.
"On April 14 or 15 I'll have a gym fight with Takam. We'll do 12 threes and I might have to give him money.
"It will be behind closed doors, it won't be sold to the media. There won't any judges there. We'll go at it and whatever happens in the gym will stay in the gym.
"He's 6ft 2in and 18 stones so is perfect preparation for Dereck. So I'll be getting a fight in whether they want me to or not.
"I'll take time off after that, then come back into gym in May to prepare."
Chisora's European heavyweight title will be at stake when he faces Tyson Fury in July.
The belt will be added to the vacant British title up for grabs after Bulgarian Kubrat Pulev pulled out of purse bids, enabling Chisora to put it on the line against Fury.
The rematch between the domestic rivals - Fury won the first encounter on points in July 2011 - is a final eliminator to challenge WBO champion Wladimir Klitschko.
"Chisora and Fury is the biggest all-British heavyweight fight in recent years," promoter Frank Warren said.
"There's so much on the line for both men, the winner will get the number one spot to Klitschko, the vacant British title is up for grabs and now Chisora's European title has been added."
