Ronda Rousey

On Friday night, millions of MMA fans watched Ronda Rousey get brutally pummeled by defending women's bantamweight champion Amanda Nunes at UFC 207.

Nunes beat Rousey in just 48 seconds, pounding the sport's best-known fighter so badly that officials stopped the fight out of fear for Rousey's safety.

It wasn't all that long ago that Ronda Rousey was considered the most dominant female MMA fighter in the world.

That time has now decisively passed.

Tonight, Ronda Rousey will return to the UFC octagon for the first time since her crushing defeat at the hands of Holly Holm back in November of 2015.

Not only was it her first loss, the stunning upset marked only the second time one of Rousey's fights lasted longer than one round.

Ronda Rousey is arguably the only true household names to emerge from the world of MMA fighting thus far.

As the fighter who's done more than anyone else to help gain mainstream acceptance for what many once regarded as a fringe bloodsport, Rousey is invaluable to the UFC brand.

Back in November, Ronda Rousey lost her UFC bantamweight title to Holly Holm following a crushing defeat that left the reigning champ considerably worse for wear.

Of all the feuds in celebrity history, few have been more amusing or unexpected than the beef between Justin Bieber and Ronda Rousey.

As you may have heard, Ronda Rousey lost to Holly Holm in a stunning upset during Saturday night's UFC 193 in Melbourne, Australia.
