Lesnar's next challenger was Roman Reigns, who had won the Royal Rumble match to earn a title match at WrestleMania 31 on March 29. 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 after delivering a "Curb Stomp". 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.
