Teenage women's boxer Isis Sio in medically induced coma after vicious knockout loss

Isis Sio, 19, has been placed into a medically induced coma following a brutal knockout she suffered on Saturday night.

Sio was stopped by Jocelyn Camarillo just 78 seconds into their four-round light flyweight contest on a ProBoxTV card in San Bernardino, California.In the bout, Camarillo managed to back Sio onto the ring ropes and bring down Sio's guard, at which point all it took was a clean combination on a defenseless Sio to leave her face-down on the canvas. Sio initially rose to her knees, hunched over the bottom ring rope, and then fell flat onto the canvas unconscious a few seconds later.

Sio was stretchered out of the ring and rushed to the nearby Loma Linda University Health for emergency medical treatment, where she is now in a coma.
