Heyman started to speak and Rey snatched his mic in reply but Brock delivered two huge F5s to the WWE Legend.Rey's son, Dominick was watching in the front row and Brock motioned at him before dragging him over the barricades and sending him back first into the ring post and then the concrete. Brock tossed Dominick in the ring and then delivered a third F5 to Rey and another to Dominik before officials came out to stop him..@BrockLesnar is MAULING @35_dominik and @reymysterio on #RAW! pic.twitter.com/l5pQcPwH0w— WWE (@WWE) October 1, 2019Segment Rating: A+Alexa Bliss vs. Sasha BanksThe match was overshadowed by Becky Lynch's rivalry with the BossThe Boss took out Alexa right off the bat and started a screaming match with Becky Lynch who was at the commentary table.

He said he will survive Hell in a Cell and walk out as champion before offering Rey Mysterio a shot at the Universal Championship match later. He also threw out sort of an open challenge for his title later in the night as well.TONIGHT, @WWERollins is still prepared to defend his #UniversalTitle.Who's going to step up?! #RAW pic.twitter.com/VlOG8CBGB1— WWE (@WWE) October 1, 2019Robert Roode & Dolph Ziggler were out for a match with Heavy Machinery and before it began, Jerry Lawler informed us that he saw Otis eat a steak in 12 seconds.
