Isis Sio in Medically Induced Coma After First-Round Knockout in San Bernardino

Nineteen-year-old junior flyweight Isis Sio is in a medically induced coma at Loma Linda University Health medical center following a first-round knockout loss to Jocelyn Camarillo on Saturday night in San Bernardino, California. ESPN reported Sunday that ProBox TV, which promoted the card at the National Orange Show Event Center, confirmed Sio’s condition in a statement.

The bout was the opening fight on the ProBox TV card headlined by Lester Martinez vs. Immanuwel Aleem for the WBC interim super middleweight title. Camarillo (6-0, 1 KO), a 21-year-old three-time national amateur champion from Coachella, California, trapped Sio against the ropes and landed a series of punches — body shots followed by right and left hands to the head — that left Sio unconscious. The stoppage came 78 seconds into the first round.

According to veteran boxing reporter Dan Rafael, Sio was convulsing after going down and was treated in the ring for several minutes before being transported by stretcher to Loma Linda, a Level 1 trauma center located approximately five miles from the venue.

What Led to Saturday Night

Sio (1-3), from Dickinson, North Dakota, was competing 50 days after a first-round stoppage loss to Perla Bazaldua on January 30 in Long Beach, California. Her team has since clarified that the stoppage was caused by a liver shot, not a head-strike knockout. Saturday’s bout was her second consecutive stoppage defeat.

California State Athletic Commission regulations require a minimum 30-day medical suspension for a boxer who has been knocked out, with the specific length determined by the ringside physician. Sio’s team has since stated she was placed on a 45-day suspension and was cleared before accepting the Camarillo fight.

Rafael also reported that Sio’s three previous professional fights were contested at junior bantamweight, two weight classes above the junior flyweight limit at which Saturday’s bout was scheduled.

Sio turned professional in 2025. She won her second bout by unanimous decision over Katelyn Radtka after dropping her debut to Jessica Radtke Maltez. The back-to-back knockout losses to Bazaldua and Camarillo followed.

Statements

ProBox TV released a statement Sunday: “On behalf of CEO Garry Jonas and the entire ProBox family we are praying for a speedy recovery for Isis Sio. Ms. Sio is currently in a medically induced coma. Our thoughts are with her and her family at this very difficult time. Please join us in wishing for a full recovery.”

Camarillo, who told video reporter Elie Seckbach after the fight and before Sio’s condition was known that she felt both happy and “a little bit of guilt,” later posted on Instagram: “Nothing but respect. Keeping her in my prayers and wishing her healing and a full recovery.”

The story has been reported by The Washington Post, ESPN, and the Associated Press, among other outlets.

Statement From Team Isis (March 24)

“Isis is a passionate, disciplined, and well-prepared athlete who carefully evaluates each opportunity placed before her. Her decision to compete on Saturday, March 21, against Jocelyn Camarillo was not made lightly, but rather thoughtfully reviewed and analyzed prior to acceptance.

“In reference to her previous bout on January 30 against Perla Bazaldua, the result was not due to a head-strike knockout. Instead, it was caused by a liver shot. As is well understood in boxing, a direct blow to the liver can trigger an involuntary physiological response (vasovagal syncope). Because the liver is highly vascularized and rich in nerve supply, such an impact can stimulate the vagus nerve — leading to a sudden drop in blood pressure and heart rate. This may result in temporary paralysis, dizziness, and difficulty breathing.

“Please note, she was on a 45-day suspension and cleared before she accepted the fight with Jocelyn Camarillo.

“At this time, Isis remains in ICU, but she is off the ventilator and we are hopeful for her progression. We are awaiting further updates from her medical team. She is currently under the care of three specialized medical divisions who are closely monitoring her condition.

“We sincerely appreciate the continued support, thoughts, and prayers during this time.”
