Anthony Joshua and Dillian Whyte will need comprehensive title shot plans, as well as "substantial amounts of money", in order to allow Tyson Fury to fight Oleksandr Usyk for the undisputed heavyweight title.
Joshua is contractually guaranteed a rematch with Usyk for his unified WBA, WBO and IBF titles, while Whyte is the mandatory challenger for Fury's WBC belt.
But an offer from the Middle East to fund a massive unification bout between Usyk and Fury has raised the prospect of Joshua and Whyte being paid to step aside.
