With WWE Tag Team Champions The New Day joined SmackDown commentary and The Vaudevillains watching for the ramp, Enzo Amore & Big Cass battled Luke Gallows & Karl Anderson in SmackDown’s opening contest.

But considering that all four teams in attendance were set to battle in a Fatal 4-Way WWE Tag Team Match at Money in the Bank, bedlam was inevitable.

It would ultimately be Aiden English and Simon Gotch who would lite the fuse on the explosive free-for-all when they moved in on a downed Big Cass outside the ring. In response, Kofi Kingston, Xavier Woods and Big E launched a counter attack to even the odds. Within moments, the referee was forced to end the match and all four teams were battling it out — culminating in Enzo and Big Cass hurling The Vaudevillains out of the ring.

But who will walk out of the Final 4-Way with the titles? Find out June 19, only on pay-per-view.
