Overview

• At UFC 320, Macy Chiasson weighed 137.5 pounds for a bantamweight bout, was fined 25 percent of her purse, and Santos won on points.
• Santos says the promotion previously made it clear she risked losing pay and even her roster spot if she declined to face an opponent who missed weight.
• Four of Santos’ past seven scheduled opponents have missed weight, including Chelsea Chandler in 2024 at 141 pounds for a bantamweight fight.
• Santos says she was not informed in advance that Chiasson missed weight and that no apology came from Chiasson’s side until she asked for one.
• She points to past precedent like Leslie Smith’s 2018 situation after refusing an overweight opponent and calls for stronger, clearer penalties to protect fighters who make weight.
