Oleksandr Usyk and Daniel Dubois are reportedly finalising a deal for their rematch.
Organisers are targeting a July 12 date at Wembley Stadium, with all four major sanctioning body belts on the line.
That is according to Ring Magazine, which reports that both sides are now crossing the t’s and dotting the i’s to get the fight done in London.
When asked if the fight was over the line, Warren told talkSPORT: “Not at the moment, nothing done at all.
“There have been talks, but nothing is done yet. Talking goes on, and I hope it comes true.”
This comes after an exemption request was lodged to the WBO last week to allow Usyk vs Dubois to come before a mandatory fight between Usyk and interim champion Joseph Parker.
WBO president Gustavo Olivieri told Sky Sports: “There is a petition before the Championship Committee to consider a Usyk-Dubois unification to consolidate the heavyweight championships.
“Therefore, upon an official ruling regarding this matter, we will publicly announce the official decision, including Parker’s mandatory status, if that be the case.”
The WBO ordered Usyk to defend his titles against Parker after knocking out Martin Bakole in February.
In the days that followed, the IBF confirmed that they would order Dubois to defend his belt against his mandatory, Derek Chisora, by April 22.
But that won’t come into play if the WBO Championship Committee votes to allow Usyk vs Dubois to come first.
The Championship Committee’s decision has yet to be publicly disclosed at the time of writing, although the Ring reports that Dubois vs Usyk will be an undisputed heavyweight title fight.
Usyk unified the glamour division last May by beating Tyson in their inaugural encounter.
However, he was forced to relinquish his IBF title days later in order to pursue a rematch with Fury.
As a result, Dubois was elevated from interim to full IBF world champion and defended his red and gold strap by knocking out Anthony Joshua in September.
Dubois and Usyk previously squared off in August 2023, with the Ukrainian slickster getting his hand raised via ninth-round knockout.
En route to the stoppage, Dubois floored Usyk for several minutes with a shot that divided fans.
Some claimed that the shot, which decked Usyk for several minutes, was a legal body shot, while others insisted it had strayed low.
Ultimately, the referee deemed it an illegal punch and gave Usyk four minutes to recover before rebounding to stop Dubois with a stiff jab.
