After shocking the boxing world by thrashing Anthony Joshua back in early June, handing the Brit his first professional loss, it is being reported that Andy Ruiz Jr is refusing to sign off on a rematch in Saudi Arabia, unless he is granted a 'significantly higher purse.'

Currently holding the WBA, IBF and WBO heavyweight championships, Ruiz is on top of the boxing world and so believes that he is worth much more than what is currently being offered to him.

On August 9 last week, it was announced that Joshua v Ruiz II had been scheduled to happen on December 7 in the town of Diriyah, Saudi Arabia after investors had managed to pool a reported £83 million to enable the fight go ahead. 

This includes a reported £8 million for Ruiz which he had initially agreed to, though, new details suggest that he is not so happy with this amount anymore. 

The Athletic, according to talkSPORT, reports that the Mexican-American "isn't expected to sign off on the rematch in Saudi Arabia unless he's guaranteed a significantly higher purse."

Despite the fact that Ruiz had decimated Joshua in their first bout in New York City's famous Madison Square Garden, the 29-year-old signed off on a rematch clause which means that he could end up with only half of what AJ receives. 

Previously, Ruiz has also voiced his concerns at a possible rematch taking place in the UK, after Joshua suggested that it could happen in Cardiff, insisting that the rematch takes place either back in the United States or neutral territory.

Even though Joshua was demolished in New York, it is thought that he made £18 million while Ruiz took a comparatively small £5 million after replacing Jarrell Miller, who had failed a drugs test prior to the fight. 

It's also reported that yet again, Joshua will take home a career-high payday from the Middle East match-up, so it's not difficult to see why Ruiz is so concerned.
