At WrestleMania, John Cena will defeat Rusev, ending his undefeated streak and his reign as United States Champion. Cena won't be done with the Super-Athlete, though -- in addition to having a rematch clause, Rusev will also have all of his hatred and vengeance focused on the 15-time World Champion. Cena will come out for a promo, taking the crowd's booing in stride, and admit that he didn't know if he could still compete at a top level -- but he proved everyone wrong, even himself. He'll say it's an honor to represent the United States as its champion once again, but before he can go any further, he'll be interrupted by a shrieking Lana. Her presence will be a diversion for Rusev, who will attack Cena and beat him viciously -- slamming him with chairs and putting him through a table -- en route to a gimmick rubber match at Extreme Rules.
