Professional Career
Vieira burst into UFC undefeated, debuting with a split decision over Kelly Faszholz in 2016. She notched key wins like submitting Sara McMann and outpointing Cat Zingano, building a 9-2 UFC run by 2021. Main events followed: she beat ex-champ Miesha Tate and Holly Holm in close splits.

Now 15-4 overall, her 88.9% takedown defense leads bantamweight history. At 34, she’s eyeing title shots, averaging 2.6 rounds per fight over 50 rounds total. Active every seven months lately, no next bout set, but Amanda Nunes whispers circulate.
