In late December 1926, Sloan regained his first team place and appeared in 18 of the remaining 24 games of the league season. His return to the side also led to him playing all 7 matches of the club's FA Cup run, including the final where they defeated Arsenal 1–0 to become the only team from outside England to win the competition. In the their coverage of the final, the Western Mail described Sloan as "impetuous at times, but on his day a dominating personality and a good shot". Two weeks after their FA Cup victory, Sloan helped Cardiff complete a cup double by winning the Welsh Cup final, defeating Rhyl 2–0.
