Choi Doo-ho is back after a long layoff and a knee injury, and he will try to extend his late-career surge when he meets Daniel Santos in a three-round featherweight bout Saturday on the main card of UFC Fight Night 276 in Las Vegas. The event, also known as UFC Vegas 117, is set for the Meta Apex.

The prelims begin at 5 p.m. ET, with the main card at 8 p.m. ET, and Choi enters with a 16-4-1 record against Santos at 14-2-0. Choi has won his past two bouts by KO/TKO, including a Round 3 stoppage of Nate Landwehr at UFC 310 on Dec. 7, 2024, while Santos last fought at UFC 320 on Oct. 4, 2025, when he beat JooSang Yoo by Round 2 KO/TKO. Choi has not competed since then because of the knee injury that also forced him out of UFC Winnipeg.

That history gives Saturday's fight a clear edge in momentum. Santos has won four straight since dropping a unanimous decision to Julio Arce in his UFC debut at UFC 273 in April 2022, and those victories have come in different ways: two by KO/TKO and two by decision. Choi, meanwhile, is 2-3-1 in his previous six outings overall, though his recent stoppages suggest he is still dangerous when the fight turns into a strike-for-strike exchange.

The numbers point to a tight matchup. Santos lands 4.76 significant strikes per minute to Choi's 4.67, while Choi carries the better accuracy at 60.75% compared with Santos' 47.74%. Santos averages 3.01 takedowns per fight, far ahead of Choi's 1.43, but Choi owns the better takedown accuracy at 53.85% to 40.00% and also averages 0.61 submissions. Choi's 3-inch reach advantage may help him keep the fight where he wants it, but Santos has needed the judges in 3 of his past 5 fights, and Choi has gone the distance once in his past 5.

BetMGM Sportsbook lists Santos at -170 on the two-way line, with over 2.5 rounds at -110 and fight to go the distance at +150. Those prices reflect what this pairing looks like on paper: a striker-heavy featherweight bout with enough wrestling and durability to make the finish window uncertain. If Choi's return from injury holds up over three rounds, his recent knockout run makes him live in a fight that may turn on one clean sequence.
