19-Year-Old Teen Boxer Isis Sio in Medically Induced Coma After Brutal Knockout Loss

A 19-year-old women's junior flyweight boxer has been put into a medically induced coma following a first-round knockout during a fight in California. According to reports, she was rushed to Loma Linda University Health medical centre shortly after the incident for further treatment. The bout was stopped immediately by referee Ivan Guillermo following the knockout as ringside medics attended to the teen boxer in the ring.

According to an ESPN report, Isis Sio, a prospect early in her professional boxing career, was knocked unconscious during the opening fight of a ProBoxTV card on the night of Saturday, 21 March, at the National Orange Show Event Centre in San Bernardino. She had been facing unbeaten opponent Jocelyn Camarillo when a series of head shots ended the contest just over a minute into the first round.

​Medical personnel entered the ring immediately after the stoppage, where Sio was seen convulsing before being stretchered out of the arena. She was transported to Loma Linda University Health for emergency treatment.

​In a statement released Sunday, promoter ProBoxTV confirmed her condition, saying, 'Ms. Sio is currently in a medically induced coma. Our thoughts are with her and her family at this very difficult time.'

​Fight Ends in First Round

​The fight was scheduled for four rounds but ended approximately 78 seconds into the opening round after Camarillo landed multiple unanswered punches. The referee halted the bout immediately as Sio collapsed near the ropes, per World Boxing News.

​Sio, who turned professional in September 2025, entered the fight with a 1-3 record. The bout marked her second consecutive knockout loss, having also been stopped in her previous outing earlier this year.

​Camarillo, 21, remained unbeaten following the victory. In a message shared after the fight, she expressed support for her opponent, saying her 'heart is with Isis' and that she is 'wishing her a full recovery.' She said, 'All glory to God. I came prepared and gave it my all. I'm grateful for the moment, but my heart is with Isis. I'm keeping her in my prayers and wishing her a full recovery.'

​ProBoxTV issued a statement on Sunday via social media. The statement said the whole ProBox family offered prayers for Sio's fast recovery. 'On behalf of CEO Garry Jonas and the entire ProBox family we are praying for a speedy recovery for Isis Sio.' ProBoxTV also made public Sio's condition, saying, 'Sio is currently in a medically induced coma. Our thoughts are with her and her family at this very difficult time.'​

Incident Raises Concerns Over Fighter Safety

​The incident once again raised concerns about fighter safety in the sport, particularly in the lower-weight divisions where repeated head shots can accumulate quickly.

Medical protocols in professional boxing require immediate assessment following a knockout, with ringside physicians tasked with determining whether a fighter can be safely moved or requires emergency medical care.

​According to the Association of Ringside Physicians, fighters who suffer knockouts should undergo strict medical evaluation and suspension periods to reduce the risk of further brain injury.

​Past Tragedies Highlight Risks

​Serious injuries in boxing, while relatively rare, are not unprecedented. In 2019, Russian boxer Maxim Dadashev died after suffering brain injuries sustained in a bout against Subriel Matias. The tragedy led to calls for stricter safety measures, including earlier intervention by referees and improved medical oversight at ringside.

​Even celebrity-driven boxing matches have highlighted these risks. YouTuber-turned-professional boxer Jake Paul recently required a second surgery on his jaw after being knocked out by former world heavyweight champion Anthony Joshua, underscoring that serious injuries can occur at any level of the sport.
