Holly Holm faces Irene Aldana on Saturday in the main event of UFC Fight Night on "Fight Island" in Abu Dhabi, United Arab Emirates.
The main card is on ESPN, starting at 10:30 p.m. ET, and the prelims are on ESPN+ at 7:30 p.m.
Holm (13-5, 6-5 in the UFC) has lost five of her last eight fights, but each of those defeats came at the hands of someone who has owned a UFC championship belt: Amanda Nunes, Cris Cyborg, Germaine de Randamie, Valentina Shevchenko and Miesha Tate. Prior to that run, however, Holm scored the biggest victory in women's MMA history, knocking out Ronda Rousey in 2015 to become bantamweight champ.
Aldana (12-5, 5-3 UFC) has won two in a row and five of six after starting her UFC tenure 0-2. She is No. 5 in the ESPN women';s bantamweight rankings, with Holm at No. 6.
The card also features another meeting of female 135-pounders: No. 2 de Randamie faces fourth-ranked Julianna Peña.
In between those bouts is a heavyweight co-main event between Yorgan De Castro and Carlos Felipe.
