 The Celtic League in Ireland, Scotland and Wales, now known as Pro14, adopted a system identical to that of the Premiership starting in 2009–10, the season before that league expanded to include two teams from Italy.The Shaughnessy system was replaced by a six-team playoff when two South African sides joined the league in 2017–18, bringing it to its current 14-team roster.In French rugby union, a Shaughnessy-style playoff was used to determine the second of two promotion spots in the second-tier Rugby Pro D2 through the 2016–17 season, with the teams involved being the second- through fifth-placed teams, as the first-place team earned automatic promotion to the Top 14.
