This was the second event the organization hosted in
Phoenix. A featherweight bout between
The Ultimate Fighter: Latin America featherweight winner
Yair Rodríguez and former
UFC Lightweight and
Welterweight Champion B.J. Penn served as the event headliner. This was Penn's first fight in the organization in over two-and-a-half years.
Erik Koch was expected to face
Anthony Rocco Martin at the event. However, Koch pulled out of the fight on December 12 citing injury and was replaced by
Alex White.
Damian Grabowski was expected to face
Viktor Pešta at the event. However, Grabowski was removed from the bout on December 21 for undisclosed reasons and was replaced by
Alexey Oleynik. On December 29, two bouts suffered alterations:
Jussier Formiga pulled out from his bout against
Sergio Pettis and
Jordan Rinaldi from his bout against
Devin Powell. They were replaced by former
UFC Flyweight Championship challenger
John Moraga and promotional newcomer
Drakkar Klose, respectively.
Bryan Caraway was expected to face
Jimmie Rivera at the event. However, Caraway pulled out of the bout on January 4 citing an undisclosed injury. He was replaced by
Marlon Vera. Eventually, Rivera pulled from the fight as he felt going from a top-5 ranked fighter to an unranked one wouldn't make sense at that moment. ==Results==
