The 24-year-old Rincón (2-0) meets promotional newcomer Lisa Spangler (0-0) at bantamweight. After picking up back-to-back wins inside the Invicta FC cage since her pro debut in 2017, the surging Californian looks to keep momentum building with her long-awaited return to the 135-pound division.
Rincón's last fight was contested at 145 pounds due to her opponent's inability to make weight on short notice. Invicta FC 29 marks the CSA Gym-trained talent's return to the division she dominated between 2014 and 2017. Spangler, looking to play the spoiler with a historic upset for the ages, will be making her professional debut.
As for Acioly, the Brazilian is set to collide with UFC vet Pearl Gonzalez, in a flyweight affair. Gonzalez (7-3) is making a quick turnaround, after scoring a win over Kali "Pop Tart" Robbins at Invicta FC 28. The 25-year-old Acioly has dropped back-to-back starts, after opening her career with four-straight wins.
She's looking to turn the tides back in her favor, after falling short earlier this year at Pancrase 293. A talented jiu-jitsu ace, Acioly has scored two of her four pro wins by way of submission.
The nine-fight Invicta FC 29 card also features a bantamweight title fight pitting former Strikeforce champ Sarah Kaufman against Katharina Lehner. In the co-main, Pannie Kianzad battles hard-hitting bantamweight Bianca Daimoni. The event, which emanates on May 4 from Kansas City's Scottish Rite Temple, streams live and only on UFC Fight Pass.
