"If you want to see me back on the next INVICTA card, then please give a shout out to Invicta Phoenix, Invicta Fighting Championships or on twitter @InvictaFights .... I'm ready to get right back and put on a hell of a fight!!!" Kagan wrote.
The 31-year-old Kagan is coming off a loss to up-and-coming contender Rose Namajunas at Invicta FC 4, but the defeat was nothing to hang her head about.
Kagan went toe-to-toe with Namajunas for 12 minutes before getting caught in a rear-naked choke in the third round.
Invicta FC 5 official fight announcements include Vanessa Porto (15-5) vs Barb Honchak (7-2) for the inaugural Invicta FC flyweight title, and an atomweight title bout between Jessica Penne (10-1) and Michelle Waterson (10-3).
Invicta FC President Shannon Knapp said Invicta FC fans can also expect to see the return of Invicta vets Bec Hyatt (4-2), Rose Namajunas (1-0) and Veronica Rothenhausler (1-0), as well as the promotional debut of ex-Strikeforce champ Sarah Kaufman (15-2).
Knapp said Invicta FC 5 was targeted for April 13, but she'll look at other dates since the UFC will host the TUF 17 Finale on the same night.
Knapp did not rule out another partnership with Ustream despite a breakdown in the company's paywall system at Invicta FC 4, which resulted in Invicta losing thousands of dollars.
"Yeah, absolutely, would I use them again? Yeah," Knapp said of Ustream. "If we do not have a [television] deal in place at that time, I'm sure we'll go back in and give it another whirl. I mean, why not? Why wouldn't we? It's a natural progression in the business, and we ask for very minimal, fan-friendly price points."
MMA fans can tweet the matchups they would like to see to @invictafights. While it's no guarantee the top suggested matchups will be added to the card, the promotion will undoubtedly take fan picks into consideration when deciding matches to put together for Invicta FC 5.
Invicta FC 5 will be held at the Bren Events Center in Irvine, Calif., with a targeted date of mid-April.
