Holly Holm produced one of MMA's biggest upsets when she delivered a second-round head-kick to former undefeated champion Ronda Rousey Saturday night in Melbourne.

Holm followed with a couple more strikes on the ground as referee swooped in to stop the fight before Rousey could take any more damage.

The knockout ended 28-year-old Rousey's 12-fight unbeaten run and handed 34-year-old Holm the bantamweight title.

Holm, a former undisputed welterweight boxing champion, said the moment of her UFC title victory was "one of those moments that you live for."
