After nine months off, Invicta Fighting Championships will return in September with its debut on the UFC’s Fight Pass digital network.

Invicta FC and the UFC announced the news on Thursday for Invicta FC 8, which takes place Sept. 6 in the promotion’s regular home of Kansas City, Mo. With a pair of title fights at the top of the bill, the event will be Invicta’s first to stream on Fight Pass, a deal that was announced in June.

Headlining the card is an atomweight (105 pounds) title fight between champion Michelle Waterson (11-3) and Yasuko Tamada (15-8-3). The co-main event sees the vacant strawweight (115 pounds) title up for grabs as Stephanie Eggink (4-1) takes on Katja Kankaanpaa (9-1-1).

Invicta President Shannon Knapp said on a Thursday conference call with media members that the promotion “outgrew” its venue for the previous four cards, the Ameristar Casino Hotel in Kansas City. Knapp told MMAjunkie via text message that Municipal Auditorium will play host to the event.

On the heels of a content deal between the all-female MMA promotion and the UFC, Invicta FC’s full library will also be available on UFC Fight Pass. Knapp said the move to Fight Pass is an important step for the promotion as it transitions away from its previous broadcast platform. Past events were streamed via online pay-per-view and several times encountered paywall issues that forced the promotion to refund money to paying customers.

Knapp added the promotion doesn’t have a set number of events planned for UFC Fight Pass, but hoped to do more events yearly. The promotion held three events in 2012 and four this past year, but stalled this year as Knapp negotiated with a variety of potential broadcast partners.

Invicta FC’s first event reportedly drew 233,580 and its second event drew “over 250,000 viewers,” Knapp previously told MMAjunkie, which made the promotion an attractive property to cable networks. Knapp, however, stressed the importance of striking a deal that would ensure the promotion’s long-term health.

The promotion on Thursday also announced fights between Ediane Gomes (10-2) and Tonya Evinger (13-5), Tara LaRosa (21-4) vs. Roxanne Modafferi (15-11) in a trilogy fight, Irene Aldana (3-1) vs. Peggy Morgan (2-1) and Veronica Rothenhausler (1-0) vs. Charmaine Tweet (5-4) at lightweight.

Plus, DeAnna Bennett (4-0) takes on Michelle Ould (7-3), Ashley Cummins (3-2) meets Alexa Grasso (4-0), J.J. Aldrich (0-0) fights Delaney Owen (2-0) and Jodie Esquibel (3-1) takes on Jinh Yu Frey (2-0).

Waterson – “The Karate Hottie” – won the atomweight title at Invicta FC 5 when she submitted Jessica Penne in the fourth round. That ran her winning streak to five fights, including both of her Invicta bouts. But she hasn’t fought since winning the belt in April 2013.

Tamada will be making her Invicta FC debut. The nine-year pro has been fighting exclusively in her native Japan, including for the Jewels and Deep promotions. She comes in with three straight wins.

Eggink comes to Invicta after three straight wins under the XFC banner, including a submission of Angela Magana this past September. The 25-year-old Floridian will vie for the title vacated by Carla Esparza when she moved to the UFC to compete on Season 20 of “The Ultimate Fighter,” which premieres on FOX Sports 1 the following week after Invicta FC 8.

Finland’s Kankaanpaa got back on track in May with a submission win in her home country. In December at Invicta’s most recent event, she suffered her first career loss – a unanimous decision to “TUF 20” contestant Joanne Calderwood.

The current Invicta FC 8 lineup now includes:

Michelle Waterson vs. Yasuko Tamada – for atomweight title

Stephanie Eggink vs. Katja Kankaanpaa – for vacant strawweight title

Tonya Evinger vs. Ediane Gomes
