Tyson Fury has been warned Anthony Joshua will be the heavyweight kingpin even if he beats Deontay Wilder.

Fury clashes with WBC champ Wilder at the MGM Grand Garden Arena on Saturday and the winner will receive the Ring Magazine belt in recognition as the division’s No.1.

Yet Joshua’s promoter Eddie Hearn claims his man is the ­uncrowned king of the ­heavyweights because he holds the other three main belts.

Hearn claims Joshua is willing to face the winner, if he comes through his IBF mandatory against Kubrat Pulev in June, and Saudi Arabia are interested in staging the showdown.

But he knows there are many obstacles in the way of a ­unification bout and Saturday’s loser will have the option to trigger a third fight.

Hearn claims Fury’s TV deal with ESPN to fight in the States is another issue because Joshua would want to face him in the UK.

Hearn also dismissed Fury’s claims he will try to knock Wilder out because he was robbed by the judges in the first fight 14 months ago when they scored it a draw.

Fury famously rose from the canvas in the 12th round last time to create a moment of boxing folklore after Wilder chinned him, and Hearn feels the great showman fooled everyone.
