Originally posted on MMA on SI | By Drew Beaupre | Last updated May 16, 2026 10:00 AM ET

The UFC returns home to the Meta APEX in Las Vegas, NV today for a UFC Fight Night card that features two featherweight matchups at the top of the bill.

The main event will see Melquizael Costa try to continue his climb up the featherweight rankings when he takes on Arnold Allen, who is 1-3 across his last four fights but has only lost to elite UFC featherweights during that run.

The card’s co-main event could easily end up earning “Fight of the Night” honors, as featherweight action fighters Doo Ho Choi and Daniel Santos are set to square off and attempt to extend their respective winning runs.
