UFC 221: Romero vs. Rockhold

The card marked the UFC debut of Israel Adesanya, who would go on to become one of the defining champions of his era. A Middleweight clash between Yoel Romero and Luke Rockhold headlined the event after being scheduled as an interim title fight, though Romero was rendered ineligible for the belt after missing weight. The night also marked the UFC’s first appearance in Western Australia following the lifting of a long-standing cage-fighting ban.
