Casey “King” O’Neill (5-0 MMA, 0-0 UFC)

Strawweight (115lbs): 3-0 (MMA)

Flyweight (125lbs): 2-0 (MMA), Making UFC Debut

Casey O’Neill is a fighter that is extremely young in her professional career and just young in general at 23 years old. With that in mind, its not that big of a deal that the 5’6″ tall fighter moved up from 115lbs to 125lbs after her third pro MMA fight.

O’Neill was a three time Eternal MMA strawweight champion before she changed weight classes. O’Neil has both of her finishes on the ground and has had decent competition for her career so far as she looks to make her UFC debut in the flyweight division at UFC Vegas 19, against Shana Dobson.
