Dillian Whyte and Anthony Joshua could ask for PS20million to allow Tyson Fury and Oleksandr Usyk to fight.
Fury and Usyk are in negotiations for a huge-money, undisputed world heavyweight fight in the Middle East.
Anthony Joshua could ask for PS15m in order to stop fighting Oleksandr Uzyk
The fight can only take place if the next opponent -- Joshua and Whyte -- is paid millions.
It could prove difficult to arrange the queue so that the winner is facing AJ. However, it is believed that AJ will be offered PS15m and Whyte PS5m.
Joshua, 32 years old, has activated his clause to rematch Usyk, 35 for the WBA and IBF belts he lost in September to the Ukrainian.
Mandatory challenger Whyte (33 years old) is currently in legal dispute with the WBC over the split of his purse for his title shot against Fury, 33.
Eddie Hearn, the promoter who looks after Joshua and White, said: "There are people that would like to see Fury V Usyk for undisputed title -- they would be willing to spend a lot of cash for it."

"What's happening are just promises from the Middle East about doing an unified fight against Usyk, Fury, and is Dillian whyte going to step aside.
"And people who have no contractual ties – like Frank Warren's Queensberry or our Top Rank - are getting involved.
"It's a terrible situation. But hopefully it'll be sorted out. Most likely it will get sorted with a purse offer on Friday."
