Lesnar 's next challenger was Roman Reigns , who won the Royal Rumble match to earn the right to face Lesnar for the title at WrestleMania 31 . During his main @-@ event match against Reigns , Lesnar delivered multiple suplexes and was heard exclaiming , " Suplex City , bitch ! " , and thereafter " Suplex City " became one of his signature catchphrases and merchandise motifs . After Lesnar and Reigns traded a few false finishes , Rollins cashed in his Money in the Bank contract while the match was in progress , making it a triple threat ; Rollins then pinned Reigns to win the title . The following night on Raw , Lesnar tried to invoke his rematch clause and subsequently attacked commentators Booker T , John " Bradshaw " Layfield , and Michael Cole , as well as a cameraman after Rollins refused the rematch , which led to Stephanie McMahon suspending Lesnar indefinitely in storyline .
