In a rundown of what happens next, WBN looks at the implications for each of the three titles Fury has vacated.
World Boxing Association title (WBA)
Former opponent Wladimir Klitschko should have the first claim to the WBA’s title after being part of the tournament to crown one sole champion previously.
As the likes of Fury, Luis Ortiz and Ruslan Chagaev have dropped out, there’s only Lucas Browne, Fres Oquendo and Alexander Ustinov left as part of the original format.
Browne and Oquendo have been ordered to face each other for the ‘regular’ belt, meaning Klitschko should be allowed to contest the ‘super’ title due to his previous reign as WBA king.
Klitschko is being linked to facing IBF champion Anthony Joshua on December 10 and his handlers at KMG should be able to convince the WBA to allow the ‘super’ belt to be on the line as the fight is a unification.
Although Klitschko is not ranked by the IBF, WBN were told there should be no problem getting the ranking he needs to challenge Joshua due to his standing in the sport.
Ortiz being out of the picture does help Klitschko’s situation considerably, whilst Browne and Oquendo would still get their shot for the lesser strap should the latter prove his fitness.
World Boxing Organisation (WBO)
In line with the WBO rules, number one ranked Joseph Parker and second placed Andy Ruiz Jr. are in pole position to contest the belt this year.
Any attempts by KMG to refer to the contract they had in place with Fury in a bid to get their shot would depend on an agreement with Parker and Ruiz.
Parker and Ruiz would have to step aside in order for Joshua v Klitschko to have the belt on the line, which seems unlikely to happen due to several media statements from New Zealand based Duco Events.
Whether Fury was given any assurances that he would be able to fight for all his titles upon his return – would dictate whether a semi-final tournament situation would then come into play for both Joshua v Klitschko and Parker v Ruiz.
International Boxing Organisation (IBO)
Ed Levine’s International Boxing Organisation have been the most easy-going of the three bodies in this current plot, but as known supporters of Klitschko and Fury, their title could follow in the same direction as the Ukrainian.
Should Joshua v Klitschko be confirmed this week, the IBF, WBA and IBO belts may be the up for grabs in the UK clash, leaving Eddie Hearn and KMG free to promote a three-belt battle on pay-per-view.
