The offside rule is arguably the most debated and scrutinized law in football. However, to maintain the flow of the game, tactical diversity, and attacking advantage, the IFAB (International Football Association Board) has decreed that the offside law does not apply in three specific restart situations: the throw-in, the goal kick, and the corner kick.
The following is a comprehensive guide to how these restarts are awarded, applied, and the technical mechanics of the “offside shield”:
1. The Throw-in
How it is awarded:
A throw-in is awarded when the whole of the ball passes over the touchline (sideline), either on the ground or in the air. It is taken by the opponents of the player who last touched the ball.
How it is applied:
- The thrower must face the field of play and have part of each foot either on the touchline or on the ground outside the touchline.
- The ball must be delivered from behind and over the head using both hands.
Offside Exemption:
There is no offside offence if a player receives the ball directly from a throw-in. A striker can be positioned deep behind the opposition’s defensive line during the throw and receive the ball legally.
Technical Nuance: The key concept here is the “new phase of play.” Once the receiver controls the ball or makes a subsequent pass, the exemption ends. Every follow-up play is then subject to standard offside evaluation.
2. The Goal Kick
How it is awarded:
A goal kick is awarded when the whole of the ball passes over the goal line, having last been touched by a player of the attacking team, and a goal is not scored.
How it is applied and the 2019 Update:
- The ball must be stationary and is kicked from any point within the goal area (6-yard box).
- Crucial: Since the 2019 rule change, the ball is in play as soon as it is kicked and clearly moves; it no longer needs to leave the penalty area.
- Opponents must remain outside the penalty area until the ball is in play.
Offside Exemption:
There is no offside offence if a player receives the ball directly from a goal kick. If a goalkeeper or a defender delivers a long ball directly to a teammate in the opponent’s half, no offside is called, even if that player is in an offside position.
Technical Nuance: The exemption expires as soon as the first receiver makes a “deliberate play” (controlling or directing the ball). For instance, if a defender receives a short pass from the keeper, the “offside shield” for teammates further up the pitch vanishes at that moment of contact.
3. The Corner Kick
How it is awarded:
A corner kick is awarded when the whole of the ball passes over the goal line, having last been touched by a player of the defending team, and a goal is not scored.
How it is applied:
- The ball must be placed within the corner arc (a quarter-circle with a 1-meter radius).
- The ball is in play when it is kicked and clearly moves.
- Opponents must remain at least 9.15 meters (10 yards) from the corner arc until the ball is in play.
Offside Exemption:
There is no offside offence if a player receives the ball directly from a corner kick. Technical and Geometric Perspective: From an engineering standpoint, since the ball is on the goal line (zero point), it is theoretically difficult for an attacker to be “ahead” of the ball. However, because offside also concerns the position of the second-to-last defender, IFAB explicitly exempts the corner kick to avoid complex geometric disputes and to preserve the attacking team’s hard-earned advantage.
The “Directly” Clause and the Own Goal Paradox
In all these exceptions, the golden rule is that the ball must travel directly from the restart to the first receiver. If the ball touches any other player (teammate or opponent) in transit, the exemption is voided immediately.
Furthermore, there are intriguing rules regarding “own goals” from these restarts:
- Throw-in and Goal Kick: If the ball enters your own goal directly from your own throw-in or goal kick, it is not a goal. Instead, a corner kick is awarded to the opposing team.
- Corner Kick: In the rare event that a player kicks a corner directly into their own goal, the goal is actually allowed to stand.
Summary Comparison Table
| Restart Type | Offside Exemption | Technical Focus | Application Note |
| Throw-in | Yes (Directly) | New Phase of Play | Two hands / Feet on ground |
| Goal Kick | Yes (Directly) | Deliberate Play | 2019 “In-Play” Update |
| Corner Kick | Yes (Directly) | Attacking Advantage | 1-meter radius arc |
