Joshua, who has won all but one of his fights by technical knockout, last fought Sept. 22, knocking out Alexander Povetkin in the seventh round. He will be defending his WBA (Super), IBF, WBO and IBO heavyweight titles.
After Jarell "Big Baby" Miller, who was denied a boxing license by the state of New York after failing three drug test, was forced to drop out of the fight against Joshua, Ruiz took his place.
Although he isn't the big name that Miller is, Ruiz is no slouch. He will bring a 32-1 record into the fight, with his lone loss coming to Joseph Parker in December, 2016. Twenty-one of Ruiz's 32 wins have come by knockout.
