Lisa Ellis is changing promotions and weight classes.

The former Ultimate Fighter competitor has signed a deal with Invicta FC and will move back down to atomweight, Invicta announced Monday. Ellis previously competed at the inaugural Invicta show in 2012 at 105 pounds.

Ellis (15-10) went 0-2 during her UFC run, the latest loss via first-round submission to rival Bec Rawlings in May. She also fell to Felice Herrig at the TUF 20 Finale and on the reality show to Jessica Penne. Ellis, 32, lost to Penne at Invicta 1 in the best -- and bloodiest -- women's fight of 2012.

The Washington native is a pioneer of women's MMA with a career going back to 2004. She has competed in women's organizations in Japan like DEEP and for promotions like Bellator and BoDog Fight in the United States.

Invicta also announced the signings of four other fighters. Atomweights Dora Perjes of Hungary and Julia Jones of Russia inked deals, as did strawweights Aline Santos De Assis Serio and Amanda Limborco Alcantara Ribas, both of Brazil.

No fights have been determined for the new signees yet. Invicta's next event will be in November on a date and at a location yet to be determined. Cris Cyborg will be in the main event at a 140-pound catchweight.
