Anthony Joshua vs Tyson Fury: 'If either fighter loses their warm-up bout, you cannot do the fight,' warns Eddie Hearn

The richly anticipated Anthony Joshua versus Tyson Fury showdown could still be derailed if either man loses a tune-up bout beforehand, says promoter Eddie Hearn.

Both Joshua and Fury have signed to fight each other later this year. But AJ will have a comeback bout on July 25 in Saudi Arabia and Fury is looking to have a tune-up contest of his own in the summer.

Neither can afford to lose either of those fights. If they do - "it's over," says Joshua's promoter Eddie Hearn.
