Beneil Dariush and Charles Oliveira are set to face off in an eagerly awaited lightweight bout this Saturday at UFC 289. The two fighters will meet in the co-main event in Vancouver, with the fight carrying significant implications for the lightweight title. Initially scheduled for UFC 288 in May, the Dariush-Oliveira matchup had to be postponed due to an injury sustained by the Brazilian fighter, leading to the rescheduling of the bout for UFC 289.
