Hearn went on to defend his client, with fans criticising the Brixton Body Snatcher for staying silent while Fury has called both he and Usyk out.
“I see people saying: ‘Dillian Whyte has gone quiet.’ He’s training,” Hearn declared.
“Until we see a contract for that fight and they’ve paid the money, what do you expect him to do?
“This is the opportunity Dillian has wanted for a long time. He will be there.
“Will Tyson be there? We’ll see.”
Joshua and Usyk’s rematch is set to be confirmed soon with April or May pegged as potential dates, while Fury will likely defend his crown against Dillian Whyte in April 2022.
