Usyk's next fight will largely depend on what happens between Dubois and Parker.
The two-weight undisputed champion has teased a move back down to cruiserweight, but that seems more a personal desire rather than something which makes the most financial sense.
Dubois will consider himself the top contender and is desperate to have another crack at Usyk after his loss to the Ukrainian in 2023 was marred by a tight call on a low blow.
Should Dubois beat Parker, a fight with Usyk could happen in the summer of 2025.
Were Parker to win, Dubois might demand a rematch or perhaps even Joshua would emerge as a potential contender considering he beat Parker in 2018.
And what about retirement for 37-year-old Usyk?
Speaking on the 5 Live Boxing with Steve Bunce podcast, Anthony Crolla says Usyk has already achieved "immortality" in boxing.
"He should have put his gloves in the middle of the ring [after beating Fury] and walked away on a massive high," Crolla said.
"I think when [Usyk's] manager spoke, he seemed certain [Usyk] wouldn't be retiring.
"I think we'll see him fighting next year. If he does and Usyk fights Dubois again, he's expected to win when he's already stopped him but I think that's a far harder fight this time."
