Anthony Joshua has vowed to cancel his fight with Tyson Fury if Dana White takes a role as promoter.Fury and Joshua faced off for the first time in London, years in the making, ahead of their titanic heavyweight tussle on December 11 in Cardiff.Joshua has astonishingly told talkSPORT that he’d be willing to sacrifice his fight with Fury if White is declared as promoterGettyJoshua has been waiting over a decade to face Fury, but insists his loyalties would lie with Hearn if the agreement is breachedGettyBut in the background, a dispute has rumbled on over Zuffa Boxing and UFC chief White’s role in the fight.The argument has been so severe that it has even threatened to jeopardise the historic event, with AJ’s promoter Eddie Hearn demanding he is removed from proceedings.White failed to show at the press conference, but has maintained he is the promoter of the event alongside Saudi chief Turki Alalshikh.However in a bombshell interview with talkSPORT, Joshua has vowed to step away from the signed showdown if White does indeed assume the role.“My loyalty is with Eddie,” he told talkSPORT’s Spencer Oliver.“Whatever he wants to do, I’ll do it. If he wants to pull the plug [cancel the fight over White], I’d be right there tugging that plug with him.”It is an astonishing show of solidarity with Hearn, who has insisted that Joshua’s contract states White cannot be involved.His role remains undetermined, but reports have indicated he was prevented from attending the launch press conference.However, White himself suggested it was purely a clash with his own business, as he attended his own UFC Contender Series show.Joshua: ‘Get behind me, I brought this fight to the UK’Of course, White hasn’t been the only issue to prevent the fight from happening, despite the respective contracts already being signed.Joshua and Hearn led a public campaign to try and prevent the fight from landing on US shores at Madison Square Garden against the wishes of the British public.The fight now lands in the Welsh capital under a roof in front of 80,000 spectators, with issues over the start time preventing the bout from landing at Wembley Stadium.Joshua believes that it was a sticking point to get the fight agreement over the line, much like ensuring Fury had signed up to drug-testing.“Obviously the agenda was to make this fight happen by any means,” Joshua continued to talkSPORT.“But a sticking point was for it to be in the UK, and the sticking point to be enrolled in VADA testing.“There was a few sticking points but they weren’t going to be the reason for the fight to happen.“What else would I have done? Who else would I have fought? Eddie dug his heels in.“I’ve been loyal to him and he paid off, I am over the moon that is happening in the UK.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.“If people truly are behind me, they will get behind me as they will know the truth about who got this in the UK.”This is a developing story and is being updated.For the latest updates, breaking news alerts, and comprehensive analysis, refresh this page or follow our real-time news coverage by watching and listening to talkSPORT live.For broader context, explore related coverage on our homepage for the top trending stories.
