After holding its first four events in Kansas City, Kan., Invicta FC is westward bound.

Invicta FC President Shannon Knapp today told MMAjunkie.com Radio (www.mmajunkie.com/radio) that Invicta FC 5 will be held in California, possibly at Bren Center in Irvine, Calif., with a targeted April fight date.

Additionally, previously announced participant Jessica Penne (10-1) now has an opponent. She’ll put her newly won atomweight title on the line against “The Karate Hottie,” Michelle Waterson (10-3).

While the title fight initially was targeted for April 13, Knapp said she’ll look at other dates since the UFC will host the TUF 17 Finale on the same night.

“For those asking yes, the UFC just announced an April 13th date, so we will adjust that date we were looking at in April,” she tweeted. “Details coming!”

Broadcast plans for the event have not been finalized. 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 refunds to all who paid $7.95 for the webcast.

In a bittersweet twist to the issue, Ustream’s president told MMAjunkie.com Radio that record demand was responsible for the breakdown.

Knapp confirmed a previously reported fight between Vanessa Porto (15-5) and Barb Honchak (7-2) for the inaugural InvictaFC flyweight title.

Knapp said fans can also expect to see the return of promotional 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).

Penne won the atomweight title with a second-round submission of Naho Sugiyama at Invicta FC 3. The Southern California-based fighter has won her past three bouts.

Waterson also appeared at Invicta FC 3, where she earned a split decision over Lacey Schuckman. It was her fourth consecutive win.
