Association football, more commonly known as football or soccer, is a team sport played between two teams of 11 players who primarily use their feet to propel a ball around a rectangular field called a pitch. The objective of the game is to score more goals than the opposite team by moving the ball beyond the goal line into a rectangular-framed goal defended by the opposing side. Traditionally, the game has been played over two 45-minute halves, for a total match time of 90 minutes. With an estimated 250 million players active in over 200 countries and territories, it is considered the world's most popular sport.

In association football, the referee is the person responsible for interpreting and enforcing the Laws of the Game during a match. The referee is the final decision-making authority on all facts connected with play, and is the match official with the authority to start and stop play and impose disciplinary action against players and coaches during a match.
