Anthony Joshua and Oleksandr Usyk don't yet have a date set in stone for their rematch, with the situation now being complicated by an offer for Usyk to fight Tyson Fury.
A deal has been tabled from the Middle East which would see Usyk offered a huge purse to fight Fury for the undisputed heavyweight title, and Joshua paid a step aside fee.
But Hearn still believes that it's more likely fans will see Joshua face Usyk, while Fury takes on his mandatory challenger Dillian Whyte.
