UFC Fight Night: Song vs. Gutiérrez, also referred to as UFC Fight Night 233, UFC on ESPN+ 91, and UFC Vegas 83, was a mixed martial arts competition organized by the Ultimate Fighting Championship on December 9, 2023. The event took place at the UFC Apex located in Enterprise, Nevada, within the Las Vegas Metropolitan Area.
Background
Initially intended to be the UFC's second event hosted in Shanghai—and its first return to Mainland China since November 2017 following the pandemic—the event was moved to the UFC Apex in mid-November for reasons not publicly disclosed.
The headline bout showcased a bantamweight clash between Song Yadong and Chris Gutiérrez.
Originally, the four final matchups of the Road to UFC Season 2 were scheduled to occur at this event; however, these were removed after the venue relocation.
A light heavyweight contest between Zhang Mingyang and Brendson Ribeiro was postponed due to visa complications and later rescheduled for UFC 298.
Featherweight fighters Steve Garcia and Melquizael Costa, whose previous fight was canceled because of Garcia's illness, were rebooked for this card.
A flyweight matchup featuring Su Mudaerji against Allan Nascimento underwent modification when Nascimento withdrew due to injury; he was replaced by former UFC Flyweight title contender Tim Elliott, who competed at bantamweight.
A catchweight bout set at 140 pounds between Daniel Marcos and Carlos Vera was canceled as a result of Marcos encountering visa difficulties.
During weigh-ins, Luana Santos failed to make the bantamweight limit by three pounds. Her fight proceeded at catchweight status, with Santos incurring a penalty of 20% of her purse, which was awarded to her opponent, Stephanie Egger.
