WWE has five separate brands and two main roster shows, but due to the Wild Card Rule they can pop over to the other brand if they like.
We previously reported that a few Raw Superstars are backstage at SmackDown Live and apparently there are two more backstage as well. It’s not clear whether they will be used, but Brad Shepard reports that both Bray Wyatt and Finn Balor are backstage tonight.
We’ll have to see what WWE is planning for Balor and Wyatt. Those two are very likely to head toward a Summerslam match as The Eater Of Worlds breaks in his new character on the main roster.
