Herica Tiburcio Brazilian rising star Herica Tiburcio  made the most of a golden opportunity in her Invicta FC debut this past Friday at Invicta FC 10 in Houston, where she submitted Michelle Waterson  with a third-round guillotine choke to become the new atomweight champion in the event’s “Fight of the Night.” Tiburcio (9-2) immediately took the fight to Waterson (12-4) and landed kicks and punches early in the main event. She caught a kick and took down Waterson, but the defending champion countered with an armbar from her back. Tiburcio escaped to her feet and landed some nice knees in the clinch before Waterson threw her back down to the ground
