Due to Roman Reigns’ emergency surgery just one night before Night of Champions, he was unable to compete in his match against Seth Rollins.

However, after forcing official Charles Robinson to count-out Reigns and give Rollins an official win via forfeit, Mr. Money in the Bank  issued an open challenge. What Rollins didn’t anticipate was the challenge being answered by the personification of chaos – Dean Ambrose.

Out of action since a devastating Curb Stomp on top of cinder blocks on Raw weeks ago, Ambrose returned with a vendetta and vengeance on his mind. After exiting a yellow cab that tore into the back of the arena, Ambrose charged the ring and unleashed his rage at Rollins’ expense.

The unstable Superstar took the fight into the WWE Universe, prompting The Authority to order security to contain the madness. However, Ambrose leapt  off of an entrance stage video wall first onto the entire security team and  then his assault on his former Shield partner.

As the one-sided brawl found its way back to the ring, Ambrose prepared to add an exclamation point in the form of a steel chair – before being tackled by security, handcuffed and removed from the arena.

Although Ambrose most certainly rained on Rollins’ parade, The Authority protected  by Mr. Money in the Bank, well aware that with Ambrose back, Rollins has a target on him.
