The following night on Raw , Undertaker explained that he had attacked Lesnar not for ending his WrestleMania streak , but rather for Lesnar allowing Heyman to constantly taunt Undertaker about it ; this led to the two brawling throughout the arena and a WrestleMania rematch being scheduled for SummerSlam on August 23 , where Undertaker would controversially defeat Lesnar ; during the match , Undertaker tapped out to a Kimura lock by Lesnar and the timekeeper rang the bell , but the referee did not see the tapout and demanded that the match continue , which saw Undertaker then hitting Lesnar with a low blow and Lesnar passed out to Undertaker 's submission hold , Hell 's Gate . The following night on Raw , Lesnar and Heyman challenged Undertaker to an immediate rematch , only to be confronted by Bo Dallas , who mocked Lesnar about his defeat ; Lesnar then responded by delivering 3 German suplexes and an F @-@ 5 to Dallas .
