The flyweight fight was promoted to main event status after a bantamweight fight between ex-champ T.J. Dillashaw and Cory Sandhagen was postponed due to an injury to Dillashaw. Rodriguez and Waterson usually compete at strawweight, but the bout was changed to a flyweight contest due to the short-notice booking.
Rodriguez is four months removed from one of the biggest wins of her octagon career, a TKO stoppage of rising star Amanda Ribas at UFC 257. The result put her back in the win column after a decision loss to inaugural strawweight champ Carla Esparza and left her overall record at 3-1-2, with draws against Randa Markos and Cynthia Calvillo.
Waterson returns after a split decision win over Angela Hill this past September at UFC Vegas 10. The result also put her back on solid ground after back-to-back losses in bouts against Joanna Jedrzejczyk and Esparza.
