Eddie Hearn has refused to rule out signing Tyson Fury despite apparently being 'loyal' to Anthony Joshua.
Fury's future remains uncertain having reportedly completed the last fight on his £80million contract with Top Rank.
The 'Gypsy King' retained his WBC heavyweight title after an explosive sixth round knockout win against Dillian Whyte earlier this year.
The 33-year-old stopped his former sparring partner quicker than his fellow Brit did in their O2 Arena bout in December 2015 where AJ emerged victorious.

Fury - in his second reign as heavyweight champion of the world - needed just over 15 minutes to beat the Body Snatcher at Wembley Stadium on April 23.
And despite the lingering animosity between the pair, Hearn acknowledged that anything 'could happen in the future'.
Speaking to GQ, the 43-year-old said: “Tyson Fury isn’t the biggest draw in boxing, AJ still is.
Tyson Fury claims he is now retired - but is he really?
“But yes – he’s a huge star.
“But I am loyal to AJ, and I think Fury knew that when I was discussing signing him when he was 400lbs.
“He knew AJ would be my number one, and that would have been difficult.
“But you never know what could happen in the future.”
Hearn, 43, recently called Fury 'a genius' after claiming he would fight Joshua for free, should he win his rematch with Oleksandr Usyk on August 20.
He told the DAZN Boxing Show: “He’s a genius Tyson Fury, because no-one ever really questions what he says.

“On one hand, he’s just said that you’ve gotta pay him $500million to come out of retirement.
“And in the next sentence, he says he’ll fight AJ for free on non-PPV. I mean, it’s absolutely brilliant.
“The only way that Tyson Fury is gonna fight again is for a bucket load of money.
“And Tyson Fury will go to Timbuktu or Mars for a bucket load of money.
“So it doesn’t really matter what he says about free tickets and stuff like that.
“The man who doesn’t quite have the mind – he goes, ‘That is amazing, Tyson Fury wants to fight for free, what a guy, what a guy.’
“Now, anyone with a brain cell will know Tyson Fury will only fight again if he gets a shed load of money.

“The Usyk fight will not generate the kind of money that the AJ fight would.
“And I would never, ever let one of my fighters go in and fight for free.
“Tyson Fury vs Anthony Joshua is not the biggest fight in boxing, it’s the biggest fight ever in the history of the sport.
“And I will make sure that we do the right job for him [Joshua].
“Tyson Fury will wanna milk every dollar out of that fight that is available.”
