This was the first UFC event held in Nevada since
cannabis was officially removed from the state's list of banned substances. At the beginning of 2024, the Combat Sports Anti-Doping (CSAD) and Drug Free Sport organizations removed cannabis from their banned substances list when the UFC shifted its anti-doping testing from the
United States Anti-Doping Agency (USADA) to CSAD. On October 30, 2024, the
Nevada State Athletic Commission also announced its decision to remove cannabis from the state's list of prohibited substances. They stated, "The possession, use, or consumption of cannabis or cannabis products will not be considered an anti-doping violation." A flyweight bout between former two-time
UFC Flyweight Champion Brandon Moreno and
Amir Albazi was expected to headline the event. They were previously expected to meet at
UFC Fight Night: Moreno vs. Royval 2 earlier in the year but Albazi withdrew due to a neck injury. However, it was announced a day later than that report that the bout was moved to
UFC Fight Night: Moreno vs. Albazi one week before this event. A welterweight bout between
Neil Magny and
Carlos Prates served as the event headliner. A bantamweight bout between former
UFC Bantamweight Champion Cody Garbrandt and former
LFA Bantamweight Champion Miles Johns was originally scheduled for
UFC Fight Night: Royval vs. Taira. However, the bout was moved to this event for unknown reasons. In turn, Garbrandt withdrew from the bout due to undisclosed reasons and the bout was scrapped. Former
ONE Middleweight and
Light Heavyweight World Champion Reinier de Ridder made his promotional debut in a middleweight bout against
Gerald Meerschaert at this event. A women's bantamweight bout between Melissa Mullins and Montserrat Rendon was scheduled for this event. However, Rendon withdrew from the fight for unknown reasons and was replaced by promotional newcomer Klaudia Syguła. At the weigh-ins, Mullins weighed in at 137 pounds, one pound over the bantamweight non-title fight limit. The bout proceeded at catchweight and she was fined 20 percent of her purse, which went to Syguła. A welterweight rematch between
Nicolas Dalby and
Elizeu Zaleski dos Santos was scheduled for this event. The pairing previously met at
UFC Fight Night: Condit vs. Alves, which Dalby won by split decision. However, Dalby withdrew from the fight for unknown reasons and was replaced by promotional newcomer Zach Scroggin. At the weigh-ins, Scroggin weighed in at 174 pounds, three pounds over the welterweight non-title fight limit. The bout proceeded at catchweight and he was fined 20 percent of his purse, which went to Zaleski dos Santos. ==Results==
