Invicta Fighting Championships is headed back to Sin City for its 16th event.

Today the promotion announced that it will visit the Trinidad Pavilion at Tropicana Las Vegas on Friday, March 11. The event will stream live on UFC Fight Pass beginning at 8:30 p.m. ET.

The main event will see recently crowned atomweight champion Ayaka Hamasaki make her first title defense against the hard-charging Amber Brown. Japan’s Hamasaki captured gold last July with a decision win over Herica Tiburcio at Invicta FC 13. Brown, meanwhile, has won three straight in the Invicta cage, including back-to-back, first-round submission finishes. She topped Shino VanHoose at Invicta FC 15 in January via guillotine choke.

In the co-main event, the promotion will crown an interim flyweight champion as Brazilians Vanessa Porto and Jennifer Maia face off. Both fighters enter the match-up riding three-fight winning streaks. Porto was most recently in action against Roxanne Modafferi at Invicta FC 12, while Maia will return to the Invicta cage after three bouts in her home country.

Also on the card, unbeaten Mexican phenom Alexa Grasso meets former title challenger Stephanie Eggink at strawweight, recent bantamweight title combatant Irene Aldana welcomes UFC veteran Jessamyn Duke back to the promotion, veteran Roxanne Modafferi will face DeAnna Bennett in her return to the flyweight division, former atomweight champion Herica Tiburcio takes on Jinh Yu Frey, and Andrea Lee will clash with Sarah D’Alelio in her flyweight debut.

Rounding out the card, bantamweight Kelly McGill returns from injury to meet newcomer Amberlynn Orr, while debuting strawweights Ashley Greenway and Sarah Click square off.
