Stricken boxer Isis Sio’s recent fight timeline is coming into focus following the 19-year-old’s hospitalization, with her activity in the weeks before Saturday now under closer attention.
As previously reported by World Boxing News, Sio remains in a medically induced coma after a first-round knockout defeat to Jocelyn Camarillo on the undercard of Lester Martinez vs Immanuwel Aleem.
Recent Run
While the focus remains on her condition, the run of events leading into the fight tells its own story.
Sio found boxing at 15 and built at least a three-year amateur background, according to BoxRec. Like many fighters, that record does not always show the full picture.
Nothing there suggested she would be especially vulnerable to knockout defeats.
After turning over and setting up Afakasi Toas Boxing LLC, Sio pushed ahead quickly as a professional.
Her debut came against Jessica Radtke Maltez, where she was outpointed across four rounds by an opponent with one win from five.
She then picked up her only win against Katelyn Radtka in 2025.
Less than two months later, Sio returned in January 2026 and was stopped in 101 seconds by unbeaten prospect Perla Bazaldua.
Knockout Context
The finish was officially logged as a body shot, which can carry a shorter suspension — around 30 days under California rules. However, the sequence did not end there. Sio took additional head shots after the initial blow as she reacted late and took a knee.
In boxing, knockouts are usually followed by medical suspensions, often around 60 days depending on the circumstances. Clearance is required before a fighter is permitted to return.
Sio’s next fight came against Camarillo 50 days later, a former three-time national amateur champion — another step up in opposition in a short space of time following the previous loss.
Young fighters are often brought along carefully. Sio’s recent run shows how quickly those early tests can begin to stack up within the rules set by commissions and matchmakers.
As Sio continues to fight for her life, her recent timeline now sits alongside the wider safeguards and decisions that shape the sport.
Further updates on her condition are expected.
