The post-SummerSlam episode of WWE SmackDown will be held at the Mohegan Sun in Uncasville, Connecticut. The arena released new advertising for the show today, stating that the "new era" of SmackDown is on its way there. The wrestlers featured on the advertising are AJ Styles, New Day and Cesaro. Other stars listed on the arena's website include Dean Ambrose, Sami Zayn, Paige and Naomi.
Take this with a huge grain of salt, and this is most likely one of those "card subject to change" deals. I would seriously doubt that WWE already has the rosters figured out for RAW and SmackDown, and it most likely won't be finalized until the week it happens except for the top stars.
