Overview

• Prelims begin at 7 p.m. ET in the ESPN App and the main card starts at 10 p.m. ET on ESPN+ from RAC Arena in Perth on September 27.
• Ulberg enters his first scheduled five-round main event on an eight-fight winning streak since his 2021 debut loss, while Reyes arrives on a three-fight knockout resurgence.
• UFC preview materials frame the matchup as a potential springboard into the light heavyweight title picture depending on next week’s Ankalaev–Pereira rematch at UFC 320.
• Odds and staff predictions across outlets largely favor Ulberg, though analysts note Reyes could draw on the blueprint from Kennedy Nzechukwu’s stoppage of Ulberg in his debut.
• Ulberg says he is ready to "make the kill," and local TV reports say the arena is roughly half full with tickets discounted ahead of fight night.
