Ronda Rousey’s attempt to defend her title in an Open Challenge backfired when the Raw Women’s Champion drew out The Riott Squad, who dragged presumptive challenger Natalya to the top of the stage, surrounded the wounded titleholder, put the boots to The Baddest Woman on the Planet and forced The Bella Twins to run interference.

The two trios will meet at WWE Super Show-Down, but first, Ruby Riott will go one-on-one with Brie Bella on Raw. Who will pick up momentum ahead of their Six-Woman Tag Team Match? And will the Raw Women’s Champion and Nikki Bella once again find themselves at odds with The Riott Squad? Find out on Raw, airing live this Monday at 8/7 C on USA Network.

WWE was originally teasing Ronda Rousey defending her title against Ruby Riott at Raw but it was changed to Ruby vs Brie as seen above. The original teaser read like this:

The two trios will meet at WWE Super Show-Down, but lost in all the commotion was the fact that Ruby Riott intended to accept the challenge and make a play for Rousey’s title. Will she attempt to do so again? And, with Rousey still reeling from weeks of attacks on her ribs, will The Baddest Woman on the Planet be able to defend her hard-won championship? Find out on Raw, airing live Monday at 8/7 C on USA Network.

The only other match announced for Raw thus far is Dolph Ziggler & Drew McIntyre vs. The Revival in a Raw Tag Team Championship Match.
