The LigaPro also referred to as Ledman LigaPro for sponsorship reasons, is the second-highest division of the Portuguese football league system, after the Primeira Liga. At the end of each season, the top-finishing teams are promoted to the Primeira Liga, and the lowest-ranked teams are relegated to the third-tier Campeonato de Portugal. The division is contested nationwide by 24 teams, including the reserve sides (B teams) of several top-flight clubs. This number will be reduced to 22 in the 2016–17 season, with a further reduction to 20 teams scheduled for the 2017–18 season.
