Oleksandr Usyk's wife had a warning for Tyson Fury on Instagram.
Ukraine's WBA, IBF and WBO heavyweight world champion has agreed financial terms for an undisputed showdown with the UK's WBC king, which will see them fight on April 29 at Wembley Stadium if contracts are finalised.
Last week the fight looked very unlikely as the two boxers' representatives struggled to reach a deal behind the scenes.
However, Fury then made a shock public offer of a 70/30 purse split in his favour, which Usyk unexpectedly accepted despite previously campaigning for 50/50.
With terms agreed, Fury and Usyk’s representatives began work to finalise their contracts and get them signed.
However, on Monday the Gypsy King came out with his latest demand – for the rematch clause, which his team initially requested, to now be scrapped.
Usyk has not yet made it clear whether or not he is willing to accept this new stipulation, but his team have cast doubt over whether the fight will happen as they are not confident Fury truly wants it.
Fury's UK co-promoter Frank Warren has insisted it will get over the line.
With contracts still not signed as things stand, fans are waiting for news.
In the meantime, Usyk's wife, Katerina, has given her thoughts to her followers on Instagram.

She posted a meme to her Instagram story which carries a threatening message for Fury.
The image depicts her husband Usyk as the grim reaper, standing next to four doors with the Union Jack above.
The first three doors are open and show trails of blood leaking from within.
These have the pictures of Tony Bellew, Derek Chisora and Anthony Joshua on them - Usyk's three previously defeated British foes.
The fourth door has a picture of Fury on it.
Usyk's Grim Reaper is knocking on that door.
