Heavyweight champion Andy Ruiz and Anthony Joshua spoke to the media Thursday in New York, in advance of their December 7 rematch in Diriyah, Saudi Arabia.

Ruiz shocked the boxing world in June when he beat Joshua in a seventh round TKO at Madison Square Garden in New York City.

Ruiz’s IBF, WBA and WBO heavyweight belts will be on the line in the rematch.

This was the only loss for the 6-foot-6 Joshua, who has 22 wins, with 21 by knockout.

Ruiz comes into the rematch 32-1, with 21 of his ring victories by KO.
