[10] In turn, Trevin Giles, then Alessio Di Chirico were briefly linked as replacements to face Arroyo.

[14] Sam Alvey was scheduled to face former UFC Light Heavyweight Champion Maurício Rua at the event.

[17] In turn, Macedo was not cleared to fight by CABMMA due to severe headaches one day before the event and she was replaced by newcomer Isabella de Pádua.

[19] However, later on the same day, CABMMA executive director Cristiano Sampaio announced that due to an error of the scale used at the weigh-ins, which was set was 0.7 pounds above the official scale, Cortez and Melo were officially clear from missing weight and thus the bout proceeded at bantamweight.
