Ruiz defeated the former heavyweight champion in the seventh round back in June, at the Maddison Square in New York.
A victory will give the British fighter the chance to face either Deontay Wilder or Tyson Fury who will clash in 2020.
Joshua’s rematch with Ruiz will take place in Diriyah, Saudi Arabia on December 7.
