He would have lost his job had he engaged in a brawl with the Monday Night Messiah.Thankfully for Joe, he controlled his instincts as Seth Rollins began to cut a typical promo about how Dominik, Rey Mysterio and Aleister Black made all the wrong choices.Rollins spoke about making sacrifices and how the WWE Universe didn't accept him in his previous avatars.After signing the dotted line, @35_Dominik is officially a WWE Superstar! Next stop, #SummerSlam. #WWERaw @WWERollins pic.twitter.com/FRt9xKGRiW— WWE (@WWE) August 11, 2020Dominik cut a decent promo in response in which he alluded to Seth Rollins being selfish. They signed the respective contracts, and Seth Rollins announced that he would let Dominik use the Kendo stick in their SummerSlam match. Rollins took it one step further and said that Dominik would be allowed to use any tool from his toolbox as Dominik would otherwise stand no chance against him in a traditional wrestling match.Rollins then ordered Dominik to exit the ring as he was set to take on Humberto Carrillo in the first match of the night.UP NEXT: @humberto_wwe looks to give @35_Dominik a bit of an assist on the road to #SummerSlam as he goes one-on-one with @WWERollins! #WWERaw pic.twitter.com/jrexC6RXCd— WWE (@WWE) August 11, 2020Seth Rollins defeated Carrillo in a brief match before shifting his attention to Dominik. Murphy attacked Dominik before sending him into the ring.What followed was one of the most uncomfortable beatdowns that we've witnessed in recent memory as Seth Rollins and Murphy punished Dominik with unforgiving kendo stick shots.After signing the dotted line, @35_Dominik is officially a WWE Superstar!

It was horrific to watch as the segment accentuated the heel heat on Seth Rollins.Dominik's first night as an official WWE Superstar was incredibly painful, to say the least, but it helped shape the SummerSlam match as a quintessential babyface vs. heel match-up.LEAVE @35_Dominik ALONE!#WWERaw @WWERollins @WWE_Murphy pic.twitter.com/u60RH9H2MC— WWE (@WWE) August 11, 2020Moments after signing his WWE and #SummerSlam contract, @35_Dominik finds himself at the mercy of @WWERollins & @WWE_Murphy. #WWERaw pic.twitter.com/wccNUc5hby— WWE (@WWE) August 11, 2020*Monday Night Messiah OUT* #WWERaw @WWERollins pic.twitter.com/4HYmiVhhrt— WWE Universe (@WWEUniverse) August 11, 2020Dominik continued to impress as his selling of the brutal assault made the segment even more impactful.
