Description The event marked the promotion's first visit to Busan and the second in South Korea, after UFC Fight Night: Henderson vs. Masvidal in November 2015.
A featherweight bout between former UFC Featherweight Championship challengers Brian Ortega and Chan Sung Jung was originally slated as the event headliner. However, Ortega pulled out of the fight in early December, citing a knee injury. He was replaced by former UFC Lightweight Champion Frankie Edgar. The two were previously scheduled to meet on November 10, 2018 at UFC Fight Night: The Korean Zombie vs. RodrÃguez. However, Edgar was forced to pull out of that bout after tearing his bicep.
