On the December 3 episode of "Raw", acting general manager Baron Corbin forced Slater and Rhyno to fight each other with the stipulation that the loser will be fired. Slater won, but Corbin immediately repositioned him as a referee instead of a competitor. The following week on "Raw", Slater refereed a match between Elias and Lio Rush, where he allowed Bobby Lashley to attack Elias, leading to Rush's win. Later that same night, he attempted to cost Seth Rollins the Intercontinental Championship by helping Corbin during their match, but failed. At , Slater was scheduled to referee a TLC match between Braun Strowman and Baron Corbin, but during the match Slater took off his referee shirt (with help from Apollo Crews, Bobby Roode, Chad Gable, Finn Bálor, and Kurt Angle) and attacked Corbin, allowing Strowman to win the match. The next night, the McMahon family (Vince, Stephanie, Shane, and Triple H) announced that they will collectively be in charge of Raw and SmackDown. Corbin begged to be the permanent Raw general manager, but the family announced that he would have to win a no disqualification handicap match against Angle, Crews, Roode, and Gable with Slater as referee, which he lost. After Corbin was removed from power, Rhyno returned to aid Slater against an attack from Jinder Mahal on the December 24 episode of "Raw". The following week on "Raw", Slater and Rhyno faced Mahal and The Singh Brothers in a losing effort. At WrestleMania 35, Slater competed in the sixth annual André the Giant Memorial Battle Royal, but failed to win. On July 17, their team ended after Rhyno left WWE.
