Description
UFC Fight Night: Allen vs. Costa (also known as UFC Fight Night 276 and UFC Vegas 117) was a mixed martial arts event produced by the Ultimate Fighting Championship that took place on May 16, 2026, at the Meta Apex in Enterprise, Nevada, part of the Las Vegas Valley, United States.
Background
A featherweight bout between Arnold Allen and Melquizael Costa served as the event's headliner.
A featherweight bout between Daniel Santos and Choi Doo-ho was originally expected to take place one week earlier at UFC 328. For undisclosed reasons, the matchup was rescheduled for this event. The pairing had previously been booked for UFC Fight Night: Ulberg vs. Reyes in September 2025, but Choi withdrew for unknown reasons and the bout was cancelled.
A featherweight bout between Jordan Leavitt and Joanderson Brito was scheduled for the event. However, for undisclosed reasons, the bout was moved to UFC Fight Night: Muhammad vs. Bonfim, which is scheduled to take place two weeks later.
Nicolas Dalby and Jeremiah Wells were expected to meet in a welterweight bout at the preliminary card. However on May 7, Dalby pulled out due to an undisclosed injury, so the bout was cancelled.
A lightweight bout between Trey Ogden and promotional newcomer Thomas Gantt was originally scheduled for this event. However, Ogden withdrew due to an injury and was replaced by undefeated promotional newcomer Artur Minev.
Former LFA Light Heavyweight Champion Rodolfo Bellato was expected to face Modestas Bukauskas in a light heavyweight bout at the event. However, Bellato pulled out during fight week for undisclosed reasons and was replaced by promotional newcomer Christian Edwards in a catchweight of 215 pounds.
