Ronda Rousey is not ready to say "I quit" but should not return to the octagon, according to UFC president Dana White.
Former bantamweight champion Rousey helped raise the profile of UFC to new levels by starting her MMA career with a 12-0 record.
However, the American suffered a brutal knockout defeat to Holly Holm when defending her title, and fared no better in her latest bout when she was beaten in just 48 seconds by Amanda Nunes last December.
Rousey still remains an undoubted draw, but White has no desire to see her fight again.
"I wouldn't want to see it," White said in quotes reported by MMA Weekly.
"I don't want that to happen. I care about her. She's got enough money. She's got enough money and all that stuff.
"I don't want to see it happen. It's like with [ex-UFC light heavyweight champion] Chuck Liddell. I was hearing that Chuck was talking about fighting again. I hope that's not true."
White is still in regular correspondence with Rousey, who married UFC heavyweight Travis Browne in August, and says she seems "super happy".
And he believes the time is right for Rousey to officially call time on her career.
"She's not ready to say, 'I quit,'" White added. "She's not ready to say, 'I'm done,' for whatever reason.
"She doesn't tick like everyone else ticks. We found that out throughout the years. Whatever reason she has for not retiring, I agree [it can't be fun to keep being drug tested].
"She's got this awesome personal life. She's super happy and why put up with that aggravation anymore? Just announce it and the USADA [drug-testing] stuff stops."
