A bantamweight bout between Javid Basharat and Chris Gutiérrez was expected to take place a week earlier at UFC on ABC: Sandhagen vs. Nurmagomedov, but it was moved to this event due to unknown reasons.[5][6] During fight week, Basharat withdrew due to an injury and was replaced by promotional newcomer Quang Le, who was originally scheduled to fight on Dana White's Contender Series in September.[7]
A welterweight bout between Uroš Medić and Danny Barlow was expected to take place at this event.[8] However, on July 11, Medić announced on social media that a rib injury has forced him to withdraw from the bout.[9] Barlow faced promotional newcomer Nikolay Veretennikov instead.[10]
Two fights originally scheduled for the event were cancelled a few days before taking place: a welterweight bout between Yusaku Kinoshita and Jonny Parsons, due to Parsons withdrawing for unknown reasons; and a flyweight bout between Allan Nascimento and Jafel Filho, due to Nascimento being ill.[7]
