Ronda Rousey made waves at WrestleMania 31, but she hasn't been seen in the WWE since.

"Rowdy," an avid WWE fan, jumped over the barrier and helped Dwayne "The Rock" Johnson during his spat with Triple H and his wife, Stephanie McMahon in March 2015. Rousey got into a verbal war with the pair and then took both of them out.

Though the former UFC women's bantamweight champion has expressed great interest in returning to the company someday, her schedule has been very busy.

On top of training for her eventual return to the Octagon, Rousey's movie career is taking off as well, leaving her little time to get involved in WWE storylines.

McMahon recently spoke about the formerly undefeated UFC star's appearance in the WWE and her unfinished business with her.

"I would just say anything can happen in the WWE," McMahon told Fox Sports when asked about a potential Rousey return. "I've been chomping at the bit for a long time to have Ronda as a part of WWE, but she has a few other things on her road map I think."

Rousey lost a UFC fight for the first time in her career at UFC 193 back in November when she was knocked out by Holly Holm. The loss sent "Rowdy" on a downward spiral and she later admitted she had suicidal thoughts before being pulled from the brink by her boyfriend, fellow MMA fighter Travis Browne.

She hasn't accepted another fight since the loss, while Holm went on to lose the belt to Miesha Tate, who will defend the title against Amanda Nunes on July 9 at UFC 200 in Las Vegas.

Rousey has been training for a return to the Octagon, but president Dana White said she won't rush back to action.

As for her appearance in the WWE, White originally described it as a "one-off" at WrestleMania 31, but things could be changing. The WWE struck a cross-promotion deal with the MMA affiliate, allowing Brock Lesnar to return for one night only to face Mark Hunt at UFC 200.

The WWE may lend the UFC Lesnar and ask for another appearance from Rousey down the line in return, while there are also rumors of the company having interest in Paige VanZant.

One way or another, it seems inevitable that Rousey will find her way back to the squared circle.
