In 2017, the format was reduced to 4 teams, with the NRL citing tight schedules, distant travel and long seasons as an impediment to their participation in the Series. After the NRL negotiated with the Brisbane Broncos, it was decided that they would represent the NRL in an exhibition match vs Warrington Wolves prior to the usual Challenge game between the Super League Champions Wigan Warriors and Cronulla Sutherland Sharks, maintaining the overall Series concept. 2017 would be Super League's first victory since the series began, with Warrington winning 27-18 against Brisbane, and Wigan beating Cronulla 22-6.
