6 things you need to know before WWE SummerSlam 2019

#1: Will the Big Dog's attacker be revealed?

Reigns has been involved in a series of backstage incidents recently, and is still on the hunt for answers.

This year's SummerSlam has plenty of major stars including Brock Lesnar, Trish Stratus and Goldberg, one major player who isn't booked to compete is Roman Reigns.

Despite being one of the company's biggest stars, as well as main-eventing last year's show, the Big Dog won't be competing after a series of attacks backstage have left Reigns looking for answers.

On this week's SmackDown Live, Buddy Murphy told Roman that it was Erick Rowan responsible, though Rowan's mentor Daniel Bryan has denied the allegations.

Bryan and Reigns do have a history together, as shortly after the Big Dog won the 2015 Royal Rumble, Reigns put his WrestleMania title match on the line against Bryan at that year's Fastlane Pay Per View, and was able to overcome the eco-friendly warrior.

Interestingly, a match between Reigns and Bryan (who has been rumored to be the mastermind behind the attacks), was rumored to take place at the Pay Per View, so maybe tonight will be the night the former Universal Champion finally gets to the bottom of this mystery.
