Amanda Nunes looks to start another women's bantamweight title defense streak as she faces first-time UFC title challenger Irene Aldana in the main event of UFC 289 at Rogers Arena in Vancouver, Canada (10 p.m. ET on ESPN+ PPV, with prelims at 8 p.m. on ESPN/ESPN+ and early prelims at 7 p.m. ET on ESPN/ESPN+).
Nunes, No. 1 in ESPN's women's pound-for-pound rankings, beat Julianna Peña to reclaim the title at UFC 277 in July 2022. Aldana, ranked No. 6 in ESPN's divisional rankings, is riding a two-fight win streak with wins over Yana Santos and Macy Chiasson, respectively.
In the co-main event, lightweight contenders Charles Oliveira and Beneil Dariush square off in what could be their path to a shot at reigning division champion Islam Makhachev. Oliveira, ESPN's No. 2 lightweight, lost the title to Makhachev at UFC 280 last October. Dariush, ranked right behind Oliveira, has won his last eight fights.
