After SmackDown went off the air following John Cena and Shinsuke Nakamura’s match, Baron Corbin ran down and attacked Nakamura. Cena made the save, but Corbin took control and went to put him through the announce table. However, Cena lifted him up and nailed him with an Attitude Adjustment through the table instead. Cena then shook Nakamura’s hand and raised his arm again before leaving the ring as Nakamura’s music hit.
It seems like it could possibly be setting up a Cena vs. Corbin match at SummerSlam, since neither of them have a match yet.
