Ronda Rousey Won't Officially Retire from MMA, But She's Done

Ronda Rousey has essentially announced her retirement from MMA -- even though she won't officially say the words, "I'm retired."

It all went down on the 'Ellen' show (airs Tuesday) -- when Ellen asked Ronda if she'll ever go back to the UFC.

"I don't know," Ronda said ... "I think it's just as likely as me going back to another Olympics for judo."

FYI, Rousey won a bronze medal in judo in the 2008 Summer Olympics. She began her MMA fighting career in 2010. And let's face it, she ain't going back to judo.

"No one demanded a written resignation from me for judo and I don't really think the same thing is necessary for fighting."

"I'm just doing what I enjoy and WWE is what I enjoy right now."
