Holly Holm has her sights set on another UFC women's bantamweight title shot but she will need to overcome Ketlen Vieira to secure that goal.
Holm returned to bantamweight in 2019 but lost to then-champion Amanda Nunes via a first round TKO. She has subsequently bounced back with successive decision victories over Raquel Pennington and Irene Aldana to move to #2 in the rankings.
Nunes has since lost her belt to Julianna Pena and a rematch could be on the cards later this year with the victor likely to face the winner of Holm v Vieira.
Vieira burst onto the scene in the UFC with four successive victories, however, she's 2-2 from her last four fights and sits #5 in the division.
A unanimous decision triumph over Miesha Tate last time out got her back in the win column following a decision loss to Yana Kunitskaya.
The Brazilian's other defeat under the UFC banner came courtesy of a KO when she squared off against #3 ranked Aldana.
Nunes had been the dominant figure in the division after making her UFC debut in 2013, winning the bantamweight title in her seventh fight and going on to defend it successfully on five occasions.
However, she lost her strap to Pena at UFC 269 and, unless Nunes earns some revenge in an expected rematch later this year, the likes of Holm and Vieira will be gunning for the Venezuelan Vixen.
Holm already knows how it feels to be at the top of the division, winning the bantamweight belt after beating Ronda Rousey by KO at UFC 193, but she lost the title next time out at the hands of Tate.
The Preacher's Daughter fell short in her second title shot against Nunes but she's looking to stitch together another run towards the gold.
Vieira is yet to get a look in for the bantamweight title but she could potentially be just one victory away from stepping into the frame.
Holly Holm - 19 fights, 14 wins (8 KOs), 5 defeats.
Ketlen Vieira - 14 fights, 12 wins (2 KOs), 2 defeats.
Sunday's event takes place at the UFC Apex in Enterprise, Nevada.
