Invicta FC 21 has lost a former title challenger, but has added a title fight.

With the uncertainty surrounding the promotion’s current featherweight titleholder, Cristiane “Cyborg” Justino, the promotion has revealed that the main event between Megan Anderson and Charmaine Tweet will now be a five-round affair for the interim featherweight championship.

The fight will be Anderson’s first attempt at an Invicta belt. The Australia native, who transplanted to Kansas City, has won three straight fights leading into the title match-up. She has scored back-to-back, first-round knockout victories over Peggy Morgan and Amanda Bell.

Canada’s Tweet will battle for the title for a second time. She fell to the aforementioned Cyborg in under a minute at Invicta FC 11. Tweet returned to the promotion in May, delivering a first-round finish of Latoya Walker via spinning backfist to extend her current winning streak to three.

The promotion has also announced that former strawweight title challenger DeAnna Bennett has been forced out of her bout with Jodie Esquibel. Bennett will be replaced by the undefeated Kali Robbins, and the match-up with Esquibel will now be a 120-pound catchweight. Hailing from Milwaukee, Robbins has finished all four of her professional wins, including three inside the first round.

Invicta FC 21 will take place Saturday, Jan. 14 from the Scottish Rite Temple in Kansas City, Mo. The event will stream on UFC Fight Pass.
