Indirect Free Kick – a free kick that is awarded at the spot of the infraction for other fouls that are judged not to be serious such as obstruction, dangerous play or charging (non-contact fouls), as well as for offside. Indirect kicks must touch another player (either team) before the ball goes into the net in order to score.
Offside – A violation that occurs when an offensive player is closer to the opponent’s goal than both the ball and the second-to-last opposing player at the time that the ball is passed to the offensive player by his or her teammate. Players cannot be called offside if they are in their own half of the field or if they receive the ball from a throw in, corner kick, or goal kick. When a player is called offside, the opposing team is awarded an indirect free kick. A player does not have to have the ball or be part of the play to be considered offside. A player can be considered offside if he is in an offside position at the time of the pass and his position or movement pulls a defensive player away from the attack.

Sending off – an ejection resulting from a player being shown a red card.
Throw-in – a way to restart play when the ball goes out over the sidelines. The team that did not touch the ball last is allowed an overhead throw.
