Ronda Rousey knocked out by Holly Holm in UFC title upset
Holly Holm stunned reigning champion Ronda Rousey to win the Ultimate Fighting Championship bantamweight title in Melbourne.
Rousey, 28, had won her previous 12 bouts and is considered the most feared female prize fighter in the world.
But fellow American Holm delivered a knockout head kick 59 seconds into the second round, plus several blows to the head, and the referee stopped the bout.
UFC pundit Joe Rogan called it the biggest upset in the sport's history.
It leaves multiple boxing world champion Holm, 34, undefeated in the mixed martial arts sport, with a 10-0 record.
