This wasn't supposed to happen. Ronda Rousey was unstoppable. She had beaten her last four UFC opponents in a total time of two minutes and 10 seconds. She was undefeated.
Until Saturday night.
At UFC 193 in Melbourne, Australia, women's bantamweight contender and renowned boxing expert Holly Holm put on a striking clinic before sending Rousey to the floor in the second round with a brutal kick.
She then blasted Rousey into unconsciousness as referee Herb Dean rushed in to stop the fight.
Rousey moves to 12-1 in her UFC career. Holly Holm is 10-0. She's also the new women's bantamweight champion of the world.
