The fight was scheduled for four rounds but was over in 78 seconds after Camarillo connected with four unanswered power shots to the defenseless Sio's head.

Sio collapsed to the bottom rope and the fight was immediately waved off by referee Ivan Guillermo. She was seen convulsing and being stretchered out of the ring.

Sio is in the intensive care unit of Loma Linda University Health Medical Center, according to event promoter ProBoxTV, which shared a statement Sunday with an update on Sio’s condition.

"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."

Sio, from Dickinson, North Dakota, made her pro debut in September and came into the fight against Camarillo with one win in three fights. She was coming off a first-round knockout loss due to body punches in January.

"My heart is with Isis and keeping her in my prayers and wishing her a full recovery," Camarillo said on social media.

Camarillo (6-0, 1 KO) is a 21-year-old from Indio, California, signed with Jake Paul’s Most Valuable Promotions.

“Lord Jesus, we come before you with faith and urgency, lifting up Isis into your loving hands," Camarillo went on. "Lord, you are the ultimate healer, the great physician, and we ask for you divine touch over her body in Jesus mighty name, amen. Please keep Isis in your prayers.”

The Camarillo-Sios fight took place on the card headlined by Lester Martinez vs. Immanuwel Aleem.
