Overview
- Multiple outlets corroborated that Casey O'Neill is booked to fight Eduarda Moura at UFC 331, which the UFC set for Sept. 19 at Crypto.com Arena in Los Angeles.
- O'Neill returns to a midcard spot after two recent wins and a March first-round knockout that followed a near two-year layoff for an ACL injury.
- Moura arrives with a 3-2 UFC record but has missed weight three times in the promotion, most recently before her February decision loss to Wang Cong.
- The bout was first reported by social-media fight reporters and later confirmed by mainstream MMA outlets, illustrating how independent tipsters and established outlets share booking news.
- With UFC 331 still lacking an announced main event, this flyweight pairing functions as a meaningful undercard test that could influence both fighters' momentum in the division.
