Anthony Joshua's rematch with Andy Ruiz Jr was announced on Friday by Eddie Hearn but according to reports the fight is already under threat with the world champion demanding more money.
Ruiz Jr's first defence of his three world heavyweight titles was announced on Friday, as a rematch with AJ on December 7th in Saudi Arabia, but it seems the Mexican wants more money.
According to The Athletic the 29-year-old is ready to reject the contract, and not sign on the dotted line, sighting a lack of money and wanting more than the $9 million he is currently being guaranteed.
The first ever Mexican heavyweight champion earned his titles on June 1st when he shocked the previously unbeaten Joshua on the Brit's debut on American soil.
Joshua was meant to face American Jarrell 'Baby' Miller but he failed a drugs test and had to be replaced, with Ruiz Jr getting the title shot after messaging Hearn on social media.
Ruiz knocked Joshua down several times at Madison Square Garden, after being knocked down himself, before the referee called the fight off.
Joshua was guaranteed a rematch straight away because of a clause in the contract from the first fight, although some have wondered whether he should get straight back in the ring with his conqueror.
There had been much discussion whether the second fight would be in Britain, America or Mexico but the announcement of the fight in Saudi Arabia seemed to placate everyone, being on neutral soil.
The rematch could now be in danger if Ruiz doesn't get guaranteed the money he will now feel he's worth being the defending champion.
It is another blow to Hearn's Matchroom Boxing stable after it was revealed that Dillian Whyte failed a drugs test in the build up to his interim heavyweight title fight with Oscar Rivas, that he won.
