Miesha Tate Says If Ronda Loses At 207 She's Done With UFC

Miesha Tate says the Ronda Rousey farewell fighting tour might be pretty short ... like, one fight short ... telling TMZ Sports Rousey will retire immediately if she loses to Amanda Nunes at 207.

Little backstory ... Tate and Rousey hate each other ... and pretty much always have.

So, when we got Miesha out in L.A. we wanted to know how she felt about the news Ronda's career is winding down ... did she shed a tear, or pop some champagne when she heard?

Apparently she did neither ... and that's because she saw the whole thing coming. In fact, Tate says if Ronda loses her next fight, she'll quit right there.

There's obviously no love lost between the two ladies ... but still, if you've heard Ronda talk lately you kinda get the feeling Tate is onto something here.
