The clash is heading to purse bids from promoters to confirm the bout between the heavyweight boxers and is seen as a key step to allow the blockbuster clash between Anthony Joshua and Tyson Fury to take place.
Joyce's manager Sam Jones said: "We are still in negotiations to get the fight done."
Matchroom promoter Eddie Hearn has expressed an interest in the fight and suggested that the winner could clash with who comes out on top between Joshua and Fury.
He told Sky Sports: "The WBO have ruled [Usyk vs Joyce] for the interim title with a view to the winner fighting the winner of AJ-Fury.
"I believe that fight will go to purse bids in a couple of weeks.
"Certainly we will be bidding for that fight. It is a good fight.
"There is history between the two of them from the amateur game.
"It is a fight that we would be interested in putting together."
Joyce recently suggested that he believes that Usyk would be prepared to fight him in the UK and is hopeful of a clash in front of a packed crowd.
He said: "I know Usyk has a lot of support in the UK and he has never been afraid of travelling. I remember fighting him in the World Boxing Super Series in East London and it felt like I was in the Ukraine. It seems like every Ukrainian based in the UK comes out to support their guy when they compete so, if fans are allowed in by the time we meet, the atmosphere will be great. His fans bring drums, they sing and shout so I am sure he will have no problem fighting here."
