UFC veteran De La Rosa meets unbeaten Postarnakova at PFL New York in July

Montana De La Rosa will carry 23 fights of UFC experience into her Professional Fighters League debut when she faces unbeaten Russian flyweight Tatiana Postarnakova at PFL New York on July 31 at UBS Arena in Long Island.

The women’s flyweight bout adds further depth to a card that already features Dakota Ditcheva vs. Denise Kielholtz and a lightweight contest between Amru Magomedov and Angel Alvarez.

De La Rosa, 31, departs the UFC having gone 6-5-1 with the promotion, collecting notable victories over Andrea Lee, Rachael Ostovich, and Ariane Lipski da Silva. Her most recent win came against Lee in 2024. A scheduled 2025 UFC bout against Luana Carolina never materialised after Carolina missed weight, which ultimately fulfilled De La Rosa’s contract and opened the door to PFL.

Postarnakova, meanwhile, arrives on a perfect 5-0 professional record, with four of those wins coming inside the first round. The 25-year-old made her PFL debut in March, earning a unanimous decision over Elora Dana. Earlier in her career she competed in Russian promotions including Nashe Delo, a quasi-MMA organisation that for much of its existence capped grappling exchanges at 30 seconds and applied exhibition designations to bouts — a context worth noting when assessing her unbeaten ledger.

De La Rosa represents a significant step up in competition for Postarnakova. A veteran of the world’s premier MMA organisation with wins over ranked opponents, the Montana native will test whether the Russian prospect’s finishing rate and unbeaten record hold up against a fighter who has shared the cage with some of the division’s best.
