Ronda Rousey makes a huge confirmation about her fight at UFC 207

Rousey is 12-1-0 in her professional fighting career.

If you want to watch Ronda Rousey in the octagon, you better take note now, because she might not be fighting for that much longer.

In an appearance on The Ellen Show on Tuesday, Rousey (12-1-0) made a couple of big statements about how her UFC Women's Bantamweight title fight at UFC 207 with Amanda Nunes.

"This is definitely one of my last fights," Rousey said when prompted about how much longer she would stay in mixed martial arts. "Everybody better watch because the show isn't going to be around forever."

Rousey's career took a huge downturn a year ago when she lost her first professional fight to Holly Holm in a stunning upset at UFC 193. Many wondered if that lone loss would be the end of Rousey's career, but the fighter eventually announced that she would be fighting Nunes (13-4-0) on December 30 in Las Vegas.

Rousey rose to prominence thanks to her multiple quick finishes in her fights. This included back-to-back fights against Alexis Davis and Cat Zingano that lasted a total of 30 seconds. UFC and Rousey's team took advantage of her success, and turned her into a superstar in popular media with multiple appearances on talk shows and in film.

Of course, all that popularity meant that Rousey had an out once she decided that she didn't want to fight any more, and it looks like that time is almost upon us. Rousey didn't outright say that the Nunes fight would be her last, but if Rousey does lose that fight... she could be done with the octagon.
