Grasso was scheduled to face Cláudia Gadelha on January 18, 2020 at UFC 246. However, on the day of the weigh-ins, Grasso weighed in at 121.5, 5.5 pounds over the non-title strawweight limit of 116 lbs. The NSAC decided to remove the fight because competitors are not allowed to compete if the weight between them is over 3 pounds. In a statement released just hours after the weigh-ins, Grasso apologized for missing weight, and declared she will now be fighting at flyweight.
