The TT Pro League (formerly known as the Professional Football League) is the Trinidad and Tobago professional league for association football clubs. It is the country's primary football competition and serves as the top division in the Trinidad and Tobago football league system. Contested by ten clubs, the league is one of the world's few football leagues that does not operate on an automatic system of promotion and relegation. Seasons run from September to May, with teams playing 18 games each totaling 90 games in the season. Most games are played in the evenings of Fridays (Super Fridays) and Saturdays (Fiesta Saturdays), with a few games played during weekday evenings.[2] Pro League clubs also play in other competitions, such as the FA Trophy, League Cup, TOYOTA Classic, Goal Shield, and Pro Bowl against domestic clubs from other divisions; and against clubs from other countries in the CFU Club Championship, the CONCACAF League and the CONCACAF Champions League.
