The Big Dog will vie for the Universal Championship at SummerSlam, but who will be his opponent?

EVANSVILLE, IN — Last week, Roman Reigns promised a big SummerSlam announcement. True to form, The Big Dog delivered. Opening Raw after a two-week absence, the former three-time WWE Champion touted his strong singles record and formally proclaimed himself as the No. 1 contender to the Universal Title at The Biggest Event of the Summer.

As you might imagine, Samoa Joe had something to say about that. The current No. 1 contender to Brock Lesnar's Universal Championship didn’t take kindly to how Reigns’ addressed him — “that guy they call Joe” — and didn’t waste any time reminding Reigns that he had never been defeated by The Big Dog.

Reigns remained unimpressed, so Joe got his attention in the form of a headbutt to the chin and a beating on the outside. And although Reigns narrowly avoided the Coquina Clutch and got the last word with a Superman Punch, Raw General Manager Kurt Angle was quick to sanction a match between the two for later in the night.
