Minor-league

Minor leagues are professional sports leagues which are not regarded as the premier leagues in those sports. Minor league teams tend to play in smaller, less elaborate venues, often competing in smaller cities. This term is used in North America with regard to several organizations competing in various sports. They generally have lesser fan bases and smaller budgets.

The minor league concept is a manifestation of the franchise system used in North American sports, whereby the group of major league teams in each sport is fixed for long periods between expansions or other adjustments, which only take place with the consent of the major league owners. In Europe, and many other parts of the world, the football leagues have many divisions below the top-flight as part of the football pyramid. In other parts of the world there is usually either a system of annual promotion and relegation, meaning that clubs have no fixed status in the hierarchy, or there is only one professional league per country in each sport, rendering the major/minor distinction irrelevant.

While there are various semi-professional football leagues, none have any affiliation with the National Football League (NFL). The NFL and its teams have had working relationships with several independent leagues in the past, including the Association of Professional Football Leagues, the Atlantic Coast Football League, and most recently, the league owned-and-operated NFL Europe. In modern times, the NFL has developed players not ready for the active roster through each team's practice squad.

Many consider the Arena Football League to have been a de facto minor league, since several NFL owners had teams in it in the mid-2000s, prior to its bankruptcy and restructuring. Arena football is played under very different conditions, and the AFL had its own minor league, af2, until 2009. Several other independent indoor football leagues that play a similar game exist.
