Cody Rhodes and John Cena signed the contract for their SummerSlam match in controversial fashion on last week's episode of SmackDown. There is a possibility that The Rock might return to the blue brand and confront Triple H regarding the events that occurred last week.John Cena shocked the wrestling world at this year's Elimination Chamber PLE in Toronto. Cena turned heel after Cody Rhodes, aligning himself with The Rock at the show. He had just won the Men's Elimination Chamber match before the turn and after Cody declined The Brahma Bull's offer to be his Corporate Champion.However, The Rock hasn't made an appearance since Elimination Chamber on WWE programming. Fans were hoping to see him at WrestleMania, but he didn't appear. Last week on SmackDown, Cody Rhodes laid out Cena after he said he won't be able to compete at SummerSlam. Cody then forcefully put the pen in Cena's hand and made him sign the contract while he was unconscious.There is a possibility that after the controversial ending of last week, The Rock could return to confront Triple H. He could say that Cena didn't sign the contract himself and could deem it void. This could create tensions between two of the most powerful men in the company. It could also start a rivalry between The Rock's TKO and Triple H's WWE.
