Source: The Wrestling Observer According to one source, an angle is likely going to be shot during the Dean Ambrose vs. Rob Van Dam WWE United States Championship match during the WWE SummerSlam Kickoff Show on Sunday night prior to SummerSlam. The source claims that the angle will either lead to a trios match featuring The Shield against The Big Show, Mark Henry and Rob Van Dam, or a regular tag-team match between Show and Henry and Roman Reigns and Seth Rollins. We're not exactly sure as of this writing as WWE is constantly changing plans. Regardless, all of the aforementioned WWE Superstars have been informed that they will be working on the actual SummerSlam pay-per-view card itself.
