Tyson Fury has called Anthony Joshua a "coward" amid stalled negotiations for their long-anticipated all-British heavyweight bout, with the fight's future in doubt as the two sides remain unable to agree a venue. Once expected to be confirmed for November, the contest now looks less certain to happen, denying fans a fight many had hoped would finally settle the pair's rivalry.

Joshua and promoter Eddie Hearn have signed a contract for the fight to take place in the UK, but organisers are said to prefer staging it in the United States, with Hearn previously warning contracts would need renegotiating if it moved abroad. Fury, 38, who beat Mariusz Wach last month to keep the fight on track, said he had agreed to every proposed location and accused Joshua, 36, of stalling and never truly wanting the fight, while his promoter Frank Warren insisted Fury remained "100%" committed and signed up.
