Many spectators think the offside rule is determined by a player's position when receiving the ball. However, a player can receive a pass behind the last defender and still not be offside, as the primary determinant is the moment the ball is passed.
Understanding how the offside rule works is important for both players and spectators. Proper timing of runs and positioning can create opportunities, while small mistakes can lead to failed attacks.
Unfortunately, offside is not as simple as looking at a player's position on the field. There are concepts of the last two defenders, the timing of the pass, and player involvement that need to be understood. Let's learn how it works so you won't be confused when the referee disallows a goal for offside.

What is the Offside Rule in Football?
Offside is one of the basic rules in football regulated by IFAB through the Laws of the Game. This rule aims to keep the game fair so that attacking players do not just wait for the ball near the opponent's goal.
Many people think the offside rule occurs when a player is in the foremost position. However, that position does not necessarily constitute an infringement if the offside conditions are not met.
A player is in an offside position if any part of their head, body, or feet (which can be used to score a goal) is nearer to the opponents' goal line than both the ball and the second-to-last opponent when their teammate passes the ball.
However, being in an offside position alone is not enough to be considered a violation of the rule. The player must also be actively involved in the play, such as receiving a pass, interfering with an opponent, or gaining an advantage from that position.
Therefore, the offside rule makes attacking strategy more dynamic. Strikers must be adept at timing their runs, while the defensive line tries to maintain its shape to trap opponents offside.

How Does the Offside Rule Work?

1. Player's Position Relative to the Ball and Opponent's Defenders
A player is in an offside position if any part of their head, body or feet (which can be used to score a goal) is nearer to the opponents' goal line than both the ball and the second-to-last opponent when a teammate passes the ball. This position is the initial basis for the referee to assess whether an offside infringement has occurred.
The two last defenders do not always consist of one defender and the goalkeeper. In certain situations, the goalkeeper may be far from the goal, making two defenders the reference for determining offside.
Position assessment only uses body parts that can be used to score a goal, such as the head, body, and feet. The hands and arms of players and goalkeepers are not counted in the offside determination process.
2. The Moment Offside Is Determined When the Ball Is Passed
Many people think offside is judged when a player receives the ball. However, the offside decision is determined precisely at the moment the ball is touched or passed by a teammate.
A player's position a few seconds after the ball travels does not affect the referee's decision. The only reference is the player's location at the moment the pass was first made.
For example, a striker can run past all defenders after the ball is passed. As long as their position is still level with or behind the last defender when the pass was given, they are still considered onside.
3. Role of Referees and Assistant Referees in Determining Offside
Assistant referees are responsible for monitoring the position of attackers and the last defensive line throughout the match. They must also pay attention to the moment when the ball is played by the attacker's teammate.
If an infringement is observed, the assistant referee will raise a flag as a signal to the main referee. The referee then decides whether to stop the play or allow it to continue.
In professional competitions, offside decisions can be reviewed using Video Assistant Referee (VAR). This technology helps ensure a player's position is more accurate, especially in very tight situations.
4. Examples of Offside Situations in a Match
For example, a midfielder sends a through pass to a striker who is already beyond the last two defenders. If that striker receives or plays the ball, the referee will declare offside.
Conversely, a striker who starts running from a position level with the last defender when the pass is made remains in an onside position. The attack can continue even if they then manage to get past all the defenders.
There are also situations where a player is in an offside position but does not play the ball or interfere with an opponent. In such conditions, the referee will not stop the game because the player is considered not actively involved.

When Is a Player Not Considered Offside?
Not all players near the opponent's goal automatically commit an offside infringement. The Laws of the Game establish several conditions that deem a player to be in a legal position, including:
- Receiving the Ball from a Goal Kick: A player cannot be penalized for offside if they receive the ball directly from a goal kick. This rule still applies even if their position is already beyond the last two defenders.
- Receiving the Ball from a Throw-in: Offside also does not apply when a player receives the ball directly from a throw-in. Therefore, this situation is often used to build an attack from the side of the field.
- Receiving the Ball from a Corner Kick: A player cannot be declared offside when receiving the ball directly from a corner kick. That's why many attackers wait in the penalty area for a chance to score.
- Being Level with the Two Last Defenders: A position level with the two last defenders is still considered onside according to the rules. In professional competitions, VAR is often used to confirm whether a player is truly level or has already crossed the defensive line.
Offside Infringement and Its Consequences
1. Interfering with Opponent's Play
A player is considered to commit an infringement if they receive or play the ball from a teammate while in an offside position. Such action indicates that the player is directly involved in the attack.
For example, a striker receives a through pass after being beyond the last two defenders. The referee will stop play and award an indirect free kick to the opposing team.
2. Obstructing Opponent's Vision or Movement
An infringement also occurs if a player in an offside position obstructs the goalkeeper's vision of the ball's trajectory. Additionally, a player who impedes the movement of an opposing defender can also be deemed to influence the play.
Even without touching the ball, such actions are still considered active involvement in the game. Therefore, the referee can give an offside decision to the attacking team.
3. Gaining an Advantage from an Offside Position
A player is also declared offside if they gain an advantage from a rebound off the crossbar, goalpost, or a goalkeeper's save after previously being in an offside position. This situation often occurs during goalmouth scrambles.
For example, a ball parried by the goalkeeper rebounds towards an attacker who is already in an offside position. If that player plays the ball, the referee will declare an offside infringement.
4. Penalty for an Offside Infringement
If an offside infringement is proven to have occurred, the referee will stop play and award an indirect free kick to the opposing team. The kick is taken from the location where the infringement occurred.
If a goal is scored from an offside situation, the goal will be disallowed. In professional competitions, this decision can be reviewed using VAR before the referee makes the final decision.
