On the October 22 episode of "Raw", Reigns took a hiatus due to his returning leukemia. Later that night, Rollins and Ambrose defeated Ziggler and McIntyre to win the Raw Tag Team Championship (making Rollins a double champion), only for Ambrose to turn on Rollins as he attacked him, igniting a feud between the two and disbanding The Shield once again. Rollins and Ambrose's reign as Raw Tag Team Champions was ended on the November 5 episode of "Raw", when Rollins lost a handicap match to AOP (Akam and Rezar). Two weeks later, on November 18, at Survivor Series, Rollins defeated United States Champion Shinsuke Nakamura in an interbrand champion vs. champion match. Towards the end of the year, Rollins continued feuding with Ambrose, which led to a title match on December 16 at the pay-per-view, where Ambrose defeated Rollins and ended his reign at 119 days. Going into 2019, Rollins failed to regain the championship from Ambrose on several occasions, including in a Falls Count Anywhere match when Bobby Lashley interfered, and in a triple threat match in which Lashley won the championship after pinning Ambrose.
