Deontay Wilder is willing to take a massive pay cut to ensure the Anthony Joshua fight happens, according to his trainer Jay Deas.
The WBC champion announced this week he had agreed to Joshua's demands and was ready to sign the contract for the heavyweight unification fight.
'We have accepted the offer from Team Joshua and look forward to coming over to fight again (last time was Audley Harrison) in front of the great United Kingdom fans, Deas told World Boxing News.
The location had proved to be one of the main issues in negotiating the fight over the past two months; Wilder's team offered Joshua a reported $50m (£37m) to fight in the USA but the 28-year-old Briton has remained adamant he wants to fight in the UK. The $50M offer for him to fight me next in the USA is still available.
Joshua had been edging closer to fighting Alexander Povetkin, the mandatory challenger to his WBA title, after talks with Wilder's representatives had slowed in recent weeks.

Thus, the task ahead of 24-year-old Austrian Dominic Thiem-competing in his first-ever Grand Slam final-seemed impossible. Nadal leaped out to a 2-0 lead before Thiem battled back with a break of his own to level the score at 2-2.
"We see this as a Wembley fight and we're quite limited in that respect", Hearn told Sky Sports on Tuesday. We can't wait. Send the contract'.
"The fact that we've lost four weeks waiting for an answer from Deontay Wilder makes a fight happening in 11 or 12 weeks of this magnitude unlikely", Hearn said. "We wanted a percentage, but we didn't think we could get it done in a quick time frame, so we said let's take what they've offered us. It's up to them to choose".
Wilder and Joshua will put their undefeated heavyweight records on the line.
Joshua told Independent.ie in March that he was keen to fight Wilder in his next fight and now it seems a deal has been done for what could be the richest fight in the sport's history.
The 28-year-old Joshua (21-0, 20 KOs) won a world title in 2016 and has made five defenses, including a 10th-round knockout of former longtime unified world champion Wladimir Klitschko in the consensus 2017 fight of the year and unifying three belts with the win against Parker on March 31. A mandatory rematch would likely take place in the U.S. "If it is before Povetkin, then it runs on October or November".
