Fouls are punished by a free kick, penalty kick, or indirect free kick. In the match report, the fouls committed by each side in each phase of the game are noted. The number of fouls reflects how serious the game was between these two teams. The type of foul matters in determining what punishment will be meted out. For example, if a player checks with an arm then this is called a "arm check". If a player checks with the head then this is called a "head check". There are several different types of head checks some that can only be done from behind while others can be done from any position on the field. A direct free kick is given to the opposing team when a player commits a direct foul. A direct foul means that you touch the ball with your hand or arms and not with your body. For example, if a player picks up the ball with his hand and throws it away then this is considered a direct foul. Free kicks are taken by players who enter the field of play during play. Indirect free kicks are also known as corner kicks. These are taken when a player is sent off or after 60 minutes have elapsed in a small-sided game. The referee signals for an indirect free kick by raising his flag or pennant. Five players form a box at the top of the 18-yard box.
