This event marked the promotion's second "Noche UFC" edition celebrating Mexican independence day after holding UFC Fight Night: Grasso vs. Shevchenko 2 the year prior.[4] It was also the first time the UFC has allowed a sponsor to have title partner status, officially rebranding it as "Riyadh Season Noche UFC", after a partnership with Saudi Arabia's General Entertainment Authority.[3]

The event told the history of combat in Mexico from the past to the future.[5] UFC chief content officer Craig Borsasi discussed the six 90-second film clips about Mexico's contribution to combat sports playing between bouts on the main card and that they were produced by film director Carlos López Estrada.[6][7] Each bout took place in a different world with images on the LED screens inside the arena.[7] White said that the budget for the production of the one-time only event exceeded $20 million compared to the approximate $2 million that is used at regular pay-per-view events.[7] Also, all but one of the fights on the card (the main event) featured a Mexican-born or Mexican-American fighter.[8] In addition, eight ring girls of Mexican descent were brought in for this event.[9]
