Football is a team sport where players try to score goals against their opponents. A game usually consists of two halves, with each half lasting forty-five minutes. A team is allowed a maximum of eleven players on the field at any one time. Any player over this number will be penalized. Substitutions are permitted, but players can only enter the field if play is stopped.
Football is one of the most popular sports in the world, with 1.3 billion people worldwide actively engaged in it. Football began as an English game but soon spread all over the world as English people emigrated and played it abroad. Fans of the game quickly formed in India and South America. The sport has become a worldwide phenomenon, with professional football players earning millions of dollars per game.
Football players can play different positions on a team. The positions of the forwards, defensive backs, and midfielders are the most obvious. The goal of the forwards is to score a touchdown. The midfielders are responsible for passing the ball to the forwards. The defense is responsible for blocking the opposition from scoring a goal.
A touchdown is the biggest goal in football. To score a touchdown, a player must carry the ball across the opposition’s goal line or catch a pass in the end zone. A touchdown scores six points, but a team can add extra points by converting a touchdown into an extra point. These extra points are called extra-point attempts.
