The prospect of a fight between Anthony Joshua and Deontay Wilder this year is fading with the American heavyweight poised to reject a lucrative offer from streaming service DAZN.

Sportsmail understands the WBC champion is edging towards turning down the $100million offer from DAZN, which was structured around a bout against his mandatory challenger Dominic Breazeale and then a pair of unification fights with Joshua, who holds the WBA, WBO and IBF titles.

The situation is not yet finalised, though as it currently stands the heavyweight picture will look distinctly underwhelming.

If Wilder stays with Showtime, who have screened his career to date, it will mean the three main men in the division will all be aligned to different broadcasters, as Tyson Fury is committed to ESPN and Joshua's next fight, against Jarrell Miller on June 1, will be shown on DAZN in the US.

Hopes of a Joshua-Wilder clash, which had subsided after a long series of failed negotiations, had grown again in the past week, with the latter having indicated he could be willing to step away from Showtime.

But it will take a late U-turn for the suggested Autumn bout to now materialise.

Wilder will announce his next move on Tuesday.
