Warren explained that Fury signed for the contest as far back as January, when the bout had originally been pencilled in for September before being pushed back. He said a planned warm-up fight for that month was scrapped following the serious accident in which Joshua lost two close friends, a setback that delayed preparations for the wider Fury bout.

Warren maintained that November remained the target date, with confirmation of the venue still to come.

Both men have since returned to action in tune-up fights. Fury beat Mariusz Wach in a low-key contest in Thailand, winning by seventh-round corner retirement, while Joshua overcame a difficult start against previously unknown contender Kristian Prenga in Jeddah, Saudi Arabia, recovering from being floored twice in the opening round to stop his opponent in the second.

With Hearn maintaining that Joshua’s camp would rather make a move to New York financially unattractive to organisers than accept the switch, and Warren insisting Fury’s side sees the fight proceeding regardless of venue, the two promoters remain some distance from resolving the issue that now threatens to delay one of the biggest fights British boxing has produced in years.
