Law 15 Throw-In Full Guide: Rules, Fouls, Offside Explained

The most important line in any Law 15 throw-in full guide is this: there is no offside from a throw-in. A throw-in is awarded to the opposing team of the player who last touched the ball before it fully crossed a touchline. The thrower has to face the field, keep part of each foot on or outside the touchline, and deliver the ball with both hands from behind and over the head.

How it works

Start with the award. The whole ball has to cross one of the two touchlines, either on the ground or in the air. If even a small part of the ball is still on the line, the ball is not out. The team that did not touch it last is given the throw at the point where it crossed.

The mechanics are stricter than they look. Part of each foot must be on the touchline or on the ground outside it. That means the thrower's feet cannot be inside the field of play. Both hands must be used, and the ball must travel from behind the head and over the top. A throw that is released from in front of the face or with one hand is not a legal throw.

The ball is in play the moment it leaves the thrower's hands. It does not need to touch another player first. If the thrower touches it again before anyone else has touched it, the referee awards an indirect free kick to the opposing team at the spot of the throw.

Key details

There are three details in Law 15 that matter more than the rest.

First, there is no offside directly from a throw-in. This is the big one. A forward can stand beyond the last defender before the ball is thrown, then dart forward as soon as the throw is released. The flag stays down. In the Premier League, with 20 clubs, 38 matches each and 380 total matches per season, that single detail changes how many attacking throw-ins are designed.

Second, a goal cannot be scored directly from a throw-in. If the ball is thrown straight into the opponents' goal, the restart is a goal kick. If it goes into the thrower's own goal, the restart is a corner. The thrower can create a goal, but only after the ball has touched another player.

Third, opponents have to give the thrower space. All opponents must be at least 2m from the point of the throw. A player who stands directly in front of the thrower and tries to block the throw is not allowed to be that close.

Common confusions

The most common confusion is the goalkeeper's hands. A goalkeeper can pick up a ball thrown directly by a teammate from a throw-in. The back-pass rule only bans handling a ball deliberately kicked by a team-mate. A throw-in is not a kick, so the keeper is allowed to catch it. This still surprises people because it looks identical to a back-pass.

Another common confusion is offside. Players often check over their shoulder when a throw-in is launched into the box and expect an offside flag. There is no offside from a throw-in. Once the ball has been touched by another player, normal offside rules return. Attackers can use the first touch from the throw to create the next phase, but they cannot stay offside after that.

Foul throws are often misunderstood too. Some players think both feet have to be on the ground. Law 15 requires only part of each foot to be on the touchline or outside it. A thrower can drag the back foot, as long as it is not over the line and inside the field. The more common mistake is lifting the back foot completely or letting the ball be released from below the head.

Why throw-ins matter in the Premier League

The Premier League uses the same Laws of the Game as every other competition. There is no separate Premier League throw-in law. But the league's structure gives throw-ins extra tactical weight. The league was founded on 20 February 1992 as the FA Premier League, and it has grown into a competition where set-piece margins decide relegation and European places.

Set-piece coaching has become a separate craft. Liverpool look for quick throw-ins to start counter-attacks, Manchester City overload the ball side of the pitch, and Arsenal use short options to beat the first press. These are trends, not official law, but they explain why the rules still matter.

The squad rules shape who is available to take those throw-ins. Each Premier League club must submit a 25-player squad list for players over 21, and at least 8 of those players must be homegrown. Under-21 players do not count against the 25. A club with deep attacking options can bring on a specialist late in a match, and with five substitutions allowed per match in a maximum of three windows plus half-time, managers can change both full-backs and wide players at the same time.

The points system makes the final minutes matter. Teams get three points for a win and one for a draw. The bottom three are relegated to the Championship, and three clubs come up, two automatically and one through the play-off. When a match is level deep into injury time, a throw-in in the attacking third can be the difference between one point and three.

In the typical European structure, the top four clubs go into the Champions League league phase, fifth place and the FA Cup winner go into the Europa League, and the League Cup winner goes into the Conference League play-off. Additional Champions League places can be earned via UEFA coefficient performance, so the exact allocation shifts from season to season. A late goal from a throw-in can move a club from fifth to fourth, or from outside the top four into it.

FAQ

Can a goalkeeper pick up a throw-in from a teammate?

Yes. The back-pass rule only applies to a deliberate kick from a team-mate, so a goalkeeper can legally handle a ball thrown directly to them from a throw-in.

Can a goal be scored directly from a throw-in?

No. If the ball goes straight into the opponents' goal, the restart is a goal kick. If it goes into the thrower's own goal, it is a corner.

Can a player be offside from a throw-in?

No. A player cannot be offside directly from a throw-in. Normal offside rules apply again after the ball has been touched by another player.

What happens if the thrower touches the ball twice?

An indirect free kick is awarded to the opposing team at the point where the throw was taken.

Key takeaways

• A throw-in is awarded to the opponent of the player who last touched the ball before it fully crossed a touchline.
• A legal throw-in requires part of each foot on or outside the touchline, both hands, and a release from behind and over the head.
• There is no offside directly from a throw-in, making it a tactical weapon in the attacking third.
• A throw-in cannot score directly. It becomes a goal kick if it goes into the opponent's goal and a corner if it goes into the thrower's own goal.
• The Premier League follows the same Law 15 as every other competition, but the league's 380-match season, squad rules and five-substitution rule give managers more ways to use throw-ins as a weapon.
