Heavyweight contender Dillian Whyte, and his promoter Eddie Hearn, expect the World Boxing Council to order a mandatory fight with WBC world champion Tyson Fury.
The contest would likely come off around March or April.
Fury is aligned with ESPN and BT Sport and co-promoted by Top Rank and Queensberry Promotions. Whyte's career is handled by Hearn's Matchroom Sport, who have an exclusive content deal with DAZN.
However, Whyte is not contractually precluded from facing Fury on another network.
But, Hearn is going to try hard to secure the promotional rights to that fight - which is why he believes the contest will end up in purse bid.
Hearn would like to stage Fury-Whyte in big UK stadium - but he anticipates offers will come in from other parts of the world.
"I don't think Tyson Fury is going to care who promotes the fight," Hearn said, according to The Mirror. "That is why I believe a purse bid is probably the most likely scenario here, I don't think Fury is going to care if Bob Arum promotes it.
"He will just be thinking whoever puts up the most money, and if I am fighter in this scenario I would just be looking to see who puts the most money up for the fight.
"But I have no problem with Dillian fighting on another promoter's show at all, and we will be with him promoting him and behind him but he wants to do it on a Matchroom show. And naturally for me this is a Wembley fight but there will be plenty of other offers from around the world too."
Whyte regained the WBC's interim-title earlier this year, with a stoppage of Alexander Povetkin. He was scheduled to face Otto Walling on October 30, before suffering a shoulder injury in training camp.
Fury retained his title earlier this month, when he knocked out Deontay Wilder in the eleventh round of their trilogy fight.
