According to a report from Mike Coppinger of The Athletic, Ruiz Jr.is not expected to sign off on the rematch unless he's guaranteed a significantly higher purse than the approximately $9 million he's been guaranteed to fight Joshua again.
Coppinger tweeted that Ruiz, who stunned Joshua June 1st with a 7th round TKO at Madison Square Garden to capture the WBA, IBF and WBO Heavyweight Titles, wants a much bigger guarantee to go all the way to the Middle East for the rematch.
