Anthony Joshua will fight in the United States for the first time on June 1 when he takes on Andy Ruiz Jr in New York.
The heavyweight will defend his WBA, IBF and WBO belts at Madison Square Garden against California-born Ruiz.
The champion has won 21 of his 22 bouts by knockout, while the only defeat of Ruiz's 33-fight career came on points against Joseph Parker.
Ruiz is hoping to make history by becoming the first heavyweight of Mexican descent to win a world title, but he goes into the fight as a major underdog.
