UFC Fight Night: Swanson vs. Ortega

UFC Fight Night: Swanson vs. Ortega (also known as UFC Fight Night 123) was a mixed martial arts event produced by the Ultimate Fighting Championship that was held on December 9, 2017, at Save Mart Center in Fresno, California.

Background
While the UFC has hosted many events in Northern California, the event marked the promotion's first visit to Fresno. Former Zuffa subsidiary Strikeforce previously contested five events in Fresno, the most recent in October 2010.

A featherweight bout between Cub Swanson and Brian Ortega served as the event headliner.

Promotional newcomer John Phillips was expected to face Eryk Anders at the event. However, Phillips was removed from the card on November 2 and was replaced by fellow newcomer Markus Perez Echeimberg.

Rani Yahya was expected to face Aljamain Sterling at this event. However, Yahya was forced to pull out from the card on November 7 due to injury. He was replaced by former WSOF Bantamweight Champion Marlon Moraes.

Bryan Caraway was expected to face Luke Sanders at the event. However, on November 20, Caraway pulled out of the fight due to undisclosed reasons. He was replaced by Andre Soukhamthath.

Carls John de Tomas and Alex Perez were expected to meet in a flyweight bout at this event. However, the CSAC elected to move the bout to the bantamweight division as they were concerned with De Tomas weight during fight week.

Benito Lopez was fined 10% of his show money by the CSAC due to shoving his opponent Albert Morales at the weigh-ins ceremony. That money will go directly to the commission.
