There’s a ‘huge likelihood’ neither Anthony Joshua nor Tyson Fury knows how much the other is getting paid for their mega-fight.That’s according to leading boxing lawyer and Three Points Law co-founder Tom Murray, who has explained to talkSPORT why the pair’s different contracts could’ve been pivotal in getting a deal over the line.AJ and Fury reportedly have a collective purse of $200m for their Netflix fight in Cardiff on December 11GettyOn Thursday, the long-awaited clash between AJ and Fury was announced for Cardiff’s Principality Stadium on December 11, live on Netflix.UFC CEO Dana White is co-promoting the event, which is set to have a collective purse of around $200million (£151m), per The Times. Fury and Joshua originally signed new contracts for their bout earlier this year, but concerns about it collapsing grew due to disagreements over the venue.However, with all those hurdles finally cleared, Murray has revealed why different contracts could’ve been the final step in negotiations to get the big announcement.AJ and Fury’s contract situation“The interesting thing here was there were two separate contracts signed — one with Fury, one with AJ,” Murray, who has previously worked with Eddie Hearn‘s Matchroom, explained on talkSPORT’s Hawksbee and Baker on Thursday afternoon.“AJ’s contract says the fight needs to take place in the UK. Fury’s contract says an unspecified location.“So there’s then this uncertainty of where this fight will take place. Turki Alalshikh was pushing for it to be held in the US because of the Netflix backing.“The Saudis are going down a route now where these fights need to make commercial sense. It’s not a time anymore where money can simply be provided for nothing in return. So having a big backer like Netflix is very important.“Fury was very much up for fighting in the US. He’s obviously had his show on Netflix, which has been very popular. It aligns quite nicely for him.“Whereas AJ was very resistant to that and wanted it to be held in the UK and preferably Wembley.‘The Gypsy King’ will be hoping to make it 37 wins in 40 professional fights when he meets Joshua in December“We then had this huge delay, pushing it back from October to November. And Wembley then comes out of the question because Wembley is a venue with no retractable roof.“Then the only option that’s left on the table given the force that Eddie Hearn and AJ put forward is to have it in the Principality Stadium in Cardiff.“Which is where we’ve settled on today.”Why AJ and Fury signed different contractsAsked to expand on why you have two different contracts, Murray added: “Often these fights don’t happen because of a disagreement over the split of the purse.“So someone will say I want 60 per cent and you can get 40 per cent. As soon as you have a contract where all three people are at the party, the other side knows what the other person’s been offered.“It doesn’t get to the point where you’re not actually concerned about the amount of money you’re getting paid. But you think it’s unfair that this guy’s getting paid 55 per cent.Murray said neither man knowing what the other was offered likely helped ‘facilitate a fight that hasn’t taken place in 15 years’AFPFury’s promoter Warren told talkSPORT it will be the biggest payday of both men’s careers ‘by far’ and more than any British boxer everGetty“So by having split contracts and individual ones, one with Fury, one with AJ, you can say to Anthony Joshua, here’s the amount of money to fight Tyson Fury. Are you happy with that? He says yes.“Tyson Fury says the same, and neither of them knows what the other one’s been offered.“And that way you facilitate a fight that hasn’t taken place in 15 years.”When asked if they may never know how much each other is getting paid, Murray added: “There’s a huge likelihood that that’s the case, yes.“I suspect [Joshua’s promoter] Hearn doesn’t know what [Fury’s promoter] Frank Warren‘s getting and vice versa.”Queensberry Promotion’s Warren later joined talkSPORT on Thursday and said he has ‘no idea’ why Fury and Joshua’s contracts are different.He confirmed it will be the biggest payday of both men’s careers ‘by far’ — more than any British boxer ever — and couldn’t mention an exact figure due to ‘confidentiality clauses’.Warren also said there is no rematch clause in the contract his team signed ‘at the moment’.Watch Boxing on DAZN*If you click a link in this boxout, we will earn affiliate revenueSign up to DAZN to access the definitive subscription for boxing fans.Upgrade to DAZN Ultimate from just £24.99/month, guaranteeing access to 185+ fights annually, a minimum of 12 pay-per-views at no extra cost, as well as every Lega Serie A match and other elite football access.Alternatively, DAZN Standard is just £15.99/month, with the caveat you will have to pay for pay-per-view events.Click here to sign up.
