Orton was able to kick out, but eventually Rollins would hit him with the RKO -- which Orton was banned from using per the pre-match stipulation -- to win his first high-profile title defense since shocking the world at WrestleMania 31.

John Cena was also successful in defending his United States Championship against Rusev in a Russian Chain Match. Both men battled to touch the fourth corner, and the "Cenation" leader came out on top after hitting the "Bulgarian Brute" with an Attitude Adjustment.

The mighty Russian kicked Lana out of the ringside area during the bout after she acknowledged the adulation she was getting from the fans. The Ravishing Russian later talked to The Authority and got Rusev a rematch with Cena at Payback next month, this time in an I Quit Match.

Another title-holder who was successful Sunday night was Nikki Bella as she came out on top of her Divas Championship match with Naomi. Bella toppled Naomi after Brie Bella kicked her in the head, leading to a Rack Attack.
