Tyson Fury has sparked more speculation his all-British heavyweight fight with Anthony Joshua is on the verge of collapse by suggesting he needs a new opponent for November. The all-British heavyweight showdown is being targeted for November, with both Joshua and Fury signing individual contracts for the contest. But the issue of where the fight takes place has caused a delay in an official announcement with organisers pushing to stage it in the US rather than Joshua's preferred location of Wembley Stadium.

In an expletive-laden video posted on Instagram, Fury claimed Joshua was backing out of the fight. Fury has twice lost to Usyk, with the two-time undisputed heavyweight champion now working with Joshua as part of his training and coaching team. Saudi Arabian promoter Sela is fronting the bill for the prospective Joshua-Fury fight, with both men signing separate contracts with the company.

Joshua's contract stipulates it must take place in the UK, leading to his promoter Eddie Hearn renegotiating details in that deal. But after London Mayor Sir Sadiq Khan made a public plea for the fight to happen at Wembley, Hearn said talks about staging it in the UK had 're-opened'. Sela and broadcaster Netflix are understood to favour New York's Madison Square Garden.

BBC Sport understands Sela has contacted the London mayor's office in recent weeks about bringing the long-awaited contest to the national stadium, but have not progressed talks further since last week. Hearn had said he hoped an announcement could happen in the coming week, but that now seems unlikely given the latest developments. A bout at Wembley may need to happen in the early hours - which would draw in a larger television audience in the US.

Khan says his team would back such a proposal.
