The most dominant champion of the modern era, Undisputed WWE Universal Champion Roman Reigns, returns to set the Rules of Engagement for SummerSlam with his unhinged cousin Jey Uso.
The United States Championship Invitational features Rey Mysterio, Sheamus, Cameron Grimes and LA Knight battling in their first step toward a future U.S. Title Match! The winner of the Fatal 4-Way Match will go on to face Santos Escobar, who won the first Fatal 4-Way Match on the July 28 edition of SmackDown. Whoever emerges victorious in that one-on-one showdown gets to challenge Austin Theory for the star-spangled title.
