Introduction
UFC Fight Night 233: Song vs. Gutiérrez took place on December 9, 2023 at the UFC Apex in Las Vegas — UFC Vegas 83 — and served as the final Fight Night card of 2023. The bantamweight main event featured No. 7-ranked Song Yadong against No. 15-ranked Chris Gutiérrez. The card was originally planned for Shanghai, China — what would have been the UFC’s second visit to the city — but was relocated to the Apex in November for undisclosed reasons.
Song dominated with a shutout unanimous decision (50-44, 50-45, 50-45), using leg kicks, takedowns, and control time to neutralise Gutiérrez completely. The co-main event saw Khalil Rountree Jr. spectacularly knock out Anthony Smith in the third round, inching closer to Chuck Liddell’s all-time light heavyweight knockout record and calling for a title shot against Alex Pereira. Tatsuro Taira earned his third UFC win with a second-round TKO.

Legacy & Impact
FN 233 closed out the 2023 Fight Night series. Song’s dominant shutout positioned him for bigger matchups in the bantamweight division. But the card’s lasting legacy belongs to Khalil Rountree Jr., whose KO of Smith launched the run that would see him challenge Alex Pereira for the light heavyweight championship at UFC 307 in October 2024 — one of the most unlikely title shots in recent memory. Tatsuro Taira’s continued rise through the flyweight division was another 2023 storyline that carried into 2024.
