UFC 279: Diaz vs. Ferguson

A chaotic fight week saw the card completely flipped on its head just days before the event. Khamzat Chimaev weighed in 7.5lbs over the Welterweight limit, forcing Kevin Holland to abandon his bout with Daniel Rodriguez and step in against Chimaev. Rodriguez was then matched with Li Jingliang, who had been scheduled to face Tony Ferguson. As a result, Ferguson faced Nate Diaz in the main event, despite Diaz initially being booked to fight Chimaev. This would mark Diaz's last fight in the UFC.
