Taila Santos returns against organizational newcomer at PFL Sioux Falls in May

One of the Professional Fighters League’s highest-ranked flyweights will be welcoming a new fighter to the roster next month.

Per sources close to the situation, the PFL has booked a women’s flyweight tilt pitting Taila Santos (22-4) against Qihui Yan (25-5) for the upcoming PFL Sioux Falls event. The two ladies will battle it out inside of the Sanford Pentagon in Sioux Falls, South Dakota, on May 2. Local athlete Logan Storley will serve in the main attraction as he takes on Florim Zendeli.

A bantamweight world title fight headlines PFL Chicago: Tune in LIVE, Saturday, April 11 at 9 p.m. ET on ESPN2.

After six-month suspension for oxandrolone and clenbuterol metabolites—anabolic agents prohibited both in and out of competition—knocked her out of competing in 2025, Santos will return to action for the first time since late 2024. The Brazilian saw her PFL tournament season come to a crashing halt as she suffered her first career stoppage loss to the hands and feet of Dakota Ditcheva. This defeat put a three-fight win streak behind the former Ultimate Fighting Championship title challenger, who celebrated decisions over Liz Carmouche and Jena Bishop while tapping Ilara Joanne earlier that year.

“Queen Kong” Yan will make her promotional debut as a well-traveled veteran in the sport, with her most recent appearances coming on the third “Road to UFC” season in 2024. While she picked up a split verdict in the quarterfinals, Danni McCormack shut her down in the semis. Before those outings, she made her stateside debut in 2021 at Dana White's Contender Series, losing by submission to Karine Silva. The 29-year-old from China posts a stellar stoppage rate of 88% as a professional, only going to decision three times across her 25 pro victories.
