The last time we saw Ronda Rousey, she had been defeated by Becky Lynch at WrestleMania 35. The ending of that bout pointed to there being a rematch down the line but the Baddest Woman on the Planet has since prioritised other projects and is reportedly keen to start a family with her husband.
While she's set to be part of Total Divas season nine next month, it's looking more and more likely that we won't see her step back into the squared circle...at least not for the time being!
WWE.com has moved Rousey from the "Current Superstars" section to the "Alumni" section where she not sits between Rob Van Dam and Rosa Mendes. WWE doesn't usually rush to do this (Nikki Bella isn't in the "Alumni" section despite announcing that she can't wrestle again) so it's either confirmation that Rousey is done or an attempt at misdirection.
If we don't see Rousey on SmackDown Live when it moves to FOX, though, we probably won't see her again in WWE for quite some time.
