Sources indicate that Eduarda Moura and Casey O'Neill are being targeted for a women's flyweight bout at UFC 331, scheduled for September 19. The matchup is in the works but has not been officially confirmed.
Moura, nicknamed "Ronda," enters as a 32-year-old Brazilian fighting out of Galpao da Luta. She holds a 12-2 record and brings a distinctly grappling-heavy approach to the cage, averaging 3.58 takedowns per 15 minutes — a rate that puts consistent pressure on opponents from the opening bell. Her striking output is more measured, landing 2.57 significant strikes per minute at a 37 percent accuracy rate, suggesting she prefers to work her way inside and control the fight on the mat.
O'Neill, a 28-year-old Scot training out of Xtreme Couture, carries an 11-2 record and is currently ranked 13th in the women's flyweight division. Known as "King," she is a notably active striker, landing 7.89 significant strikes per minute at a 52 percent accuracy rate — figures that rank among the more dangerous outputs in the division. She also mixes in a takedown threat of her own, averaging 1.4 takedowns per 15 minutes alongside 0.7 submission attempts per 15 minutes.
Why it matters
- O'Neill's elite striking volume clashes directly against Moura's elite takedown frequency, making for a sharply contrasting style matchup
- A win for either fighter would strengthen a case for moving up the flyweight rankings
- Both women share identical height at five-foot-six, removing any physical mismatch and placing the stylistic contrast front and center
- The bout remains unconfirmed, and the situation could change before UFC 331 takes shape
