There won’t be a new chapter in the mixed martial arts career of Ronda Rousey.

Rousey, 37, has not been seen in the cage since suffering a first-round TKO defeat at the hands of Amanda Nunes in late 2016; a bout that came a little more than a year after she experienced her first-ever MMA loss to Holly Holm in what was at the time considered to be one of the greatest upsets in the sport’s history.

Since then, Rousey has stepped away from combat sports and forged a path for herself in professional wrestling where she enjoyed an extended run in WWE before confirming in October of last year that she had retired from the squared circle owing to a series of concussions she sustained while competing in mixed martial arts.

And despite being linked to a comeback to either sport on several occasions, Rousey recently told the Insight podcast that her time as an active competitor is definitely over.

“Every couple years … the same rumor comes out,” she said, as noted by MMA Fighting.

“It’s nice to feel missed, I guess. But it’s not happening. I’m not neurologically fit to compete anymore at the highest level. I just can’t. You just get to a level where the neurological injuries you take accumulate over time. They don’t get better.”

She added: “When I got into MMA, I had already had dozens of concussions that I trained through,” Rousey said. “Like, not even stopped for. So that was about a decade of having concussion symptoms more often than not. So when I got into MMA, I was playing a game of zero errors.

“Then it got to the point where I was fighting more often than anybody. I had more outside of fighting responsibilities than anybody, and it just got to be lighter and lighter hits were hurting me more and more and more.

“I got to a point where I couldn’t take a jab without getting dazed, without getting concussion symptoms. It just got to a point where it wasn’t safe for me to fight anymore. I just couldn’t continue to fight at that higher level.”
