The Czech National Football League (Czech: Fotbalová národní liga, FNL) is the second level professional association football league in the Czech Republic. Before 2013 it was known as 2. liga or Druhá liga. The top two teams each season are eligible for promotion to the Czech First League. There are 16 clubs in the FNL. During the season, which runs from August to May or June, with a winter break between November and February or March, each club plays each of the other clubs twice (once at home, once away) and is awarded three points for a win, one for a draw and zero for a loss. Teams are ranked by total points, then goal difference and then goals scored. At the end of each season the top two teams are promoted to the First League, providing they obtain a license and meet league requirements, and are replaced by the two teams that finished bottom of that division. Similarly the two teams that finished at the bottom of the FNL are relegated to either the Bohemian Football League or the Moravian–Silesian Football League, based on geographical criteria. In turn, the champions of each of these regional divisions are promoted to the FNL.
