Invicta FC 37: Gonzalez vs. Sanchez was a mixed martial arts event that will be headlined by Pearl Gonzalez against undefeated Brogan Sanchez. The event was originally scheduled to feature Jinh Yu Frey defending her atomweight championship against Ashley Cummins in the main event, however on September 23, Frey was forced to withdraw due to injury causing the bout to be rescheduled. As a result, the previous co-main event of Gonzalez vs. Sanchez was moved up to become the main event.
