Chambers, an MMA star who holds a professional record of 3-1, defeated Japanese MMA phenom Mika Nagano (11-8) on the first all-female MMA card ever held in Australia.
Chambers topped Nagano via TKO in the first round of Australia's BFW 17 event held on Oct. 27, 2012. She also knocked out Claire Fryer at Rize 6 in 2010.
"I'm here to finally share with you my big news," Chambers said in her YouTube video announcing her Invicta signing. "Thanks for being patient. My big news is that I've been signed to a multi-fight contract to Invicta. I'm so excited. I can't wait to step into the cage again. Thanks for all your support."
Invicta FC has proven it is committed to bringing in the top female talent from around the world, as the promotion spares no expense to deliver explosive, star-studded cards each and every time out.
Hyatt and Chambers are both listed as strawweights, according to Sherdog.com. Chambers, however, apparently will compete in Invicta's atomweight division. Chambers' official Facebook fan page lists her fighting weight at 105-115 pounds.
Invicta FC President Shannon Knapp said on the Jan. 10 MMA Junkie Radio Show that Hyatt would be appearing at Invicta FC 5, but no word yet on who she will be fighting.
Chambers' first Invicta FC opponent is also yet to be determined. Invicta FC 5 is slated for mid-April in Irvine, California.
