A strawweight bout between Claudia Gadelha and Nina Ansaroff was officially announced for UFC 231 on Wednesday. The pay-per-view card is scheduled to take place at the Scotiabank Arena in Toronto, Canada, on Dec. 8.
The promotion has yet to officially announce a main event for UFC 231.
Gadelha (16-3), who once challenged for the UFC’s 115-pound belt, is coming off a decision victory over longtime rival Carla Esparza in June. The Brazilian strawweight scored wins over the likes of Karolina Kowalkiewicz, Valerie Letourneau, Cortney Casey and Jessica Aguilar throughout her MMA career.
