UFC 184 Rousey vs. Zingano (23x3)

: 28, 2015

A UFC Middleweight Championship bout between Chris Weidman and Vitor Belfort was expected to serve as the event headliner. The much delayed pairing was previously scheduled to take place at UFC 173 and also at UFC 181. However, on January 30, the UFC announced that Weidman had pulled out of the bout, citing an injury he sustained in training. Subsequently, a UFC Women's Bantamweight Championship bout between current champion Ronda Rousey and top contender Cat Zingano was promoted to the main event. Belfort was offered an interim title fight first against Lyoto Machida and then Gegard Mousasi as a replacement for Weidman, but he declined and stated that he would only fight for the full title.
