Invicta Fighting Championship just announced six bouts for their May 20 card in Kansas City, Mo.

The headlining flyweight bout between Vanessa Porto (18-7) and Agnieszka Niedźwiedź (9-0) is looking to be a title contender eliminator.

Porto has not competed since her meeting with the current champion, Jennifer Maia, in March of 2016, while Niedźwiedź has picked up two wins in that time, including a dominant unanimous decision victory over Christine Stanley at Invicta FC 18.

In the co-main event, fan favorite Roxanne Modafferi (20-13) returns to the Invicta cage to take on fellow veteran Sarah D’Alelio (11-6). Modafferi’s last appearance for Invicta was a razor-close decision loss to the champion Maia at Invicta FC 19. D’Alelio enters the bout with Modafferi having won her last four fights, three coming by way of submission.

Legacy Fighting Alliance’s flyweight champion, Andrea Lee (6-2), returns to Invicta to face Liz Tracey (3-1); this bout will round out the flyweight showcase at Invicta FC 23. Lee brings finishing skills to the match-up, stopping all but one opponent in six career victories. Tracy will be making her first appearance for Invicta FC after picking up a win over Christine Stanley outside the organization.

Former atomweight champion Herica Tiburcio (10-4) squares off against Tessa Simpson (5-1) at 105 pounds. Each fighter was awarded a bonus in their last outing, Tiburcio taking home “Performance of the Night” at Invicta FC 20 and Simpson notching “Fight of the Night” at Invicta FC 18.

Kickboxing and Muay Thai champion Tiffany Van Soest (0-1), looks for earn her first win in MMA. In her Invicta debut, Van Soest was submitted by Kalyn Schwartz at Invicta FC 19. Van Soest will take on Christine Ferea (1-0) in what may be a toe-to-toe striking match. Ferea scored a third-round knockout over Rachael Ostovich in her pro debut at Invicta FC 21 in January.
