1) Ball Out of Play
If the ball goes out over your touchline, then
- Stop running
- Get the flag into your correct hand (no crossovers)
- Hold it up at 45° in the direction of the team to take the throw.
- If the ref is pointing the other way, then change your direction to agree with the ref.
- Keep indicating for minimum 3 secs. Longer if can see the wrong team is lining up to take the throw.
If the ball goes out over your goal line, then
- Stop running
- Get the flag into your right hand (no crossovers)
- For a goal kick, point it straight at the goal box.
- For a corner , point your flag downwards towards the corner nearest to you. Regardless of which side the corner is to be taken from.
- If the ref is pointing the other way, then change your indication to agree with the ref.
- Keep indicating for minimum 3 secs. Longer if can see the teams are lining up against the decision.
Other situations also count as ‘interfering with play’, eg, drawing a defender but these are a bit obscure for a this basic page.
You need to run to stay level with the last defender in order to see if anyone is offside. Unless signalling, always keep your flag pointing down and pitchside so the ref can see it even when you are sprinting.
To indicate offside:
- Stop moving.
- Stand still with your flag straight up.
- Stay like that until a) the ref blows the free kick, b) the refs waves you down, c) More than 15 seconds have passed and the game has moved 3-4 plays ahead of the offence.
- Once the ref blows the free-kick for offside, then lower your flag to point to where the offence occurred as shown here.
- Stay still like that until the ball has been placed for the free kick. You are telling the ref and the players where to take the kick from.
The offside rule (simplified):
- Where are they? A player is offside if they are nearer to the opponent’s goal than both the ball and the last opponent (excluding the goalkeeper), when their team-mate plays the ball to them.
In other words, a player can’t receive the ball from a team-mate unless there is at least one defender between him and the goal (unless their team-mate is playing the ball backwards).
- What are they doing? A player is only offside if he/she is:
- interfering with play
(Eg. part of the attacking move)
- or interfering with an opponent
(Eg. preventing the opponent from defending against the attacking move)
- or gaining any advantage by being in that position.
- interfering with play
- Exceptions. A player can’t be offside
- in their own half
- directly from a goal-kick
- directly from a throw-in
- directly from a corner kick

3) Other Linesman Duties
As soon as the ref gives permission for a sub to occur, hold you flag horizontal over your head with your arms straight until the the ref signals for play to resume.
- Unseen Incidents
Keeping one eye on 22 players is an impossible task for the referee. The linesman, therefore, acts as a second pair of eyes. It is his duty to indicate when an incident occurs out of the referee’s view by holding the flag straight up.
- Better View
If the referee believes the linesman had a better view of an incident, she will consult with the linesman to determine the correct course of action.
- Penalty Kicks
The linesman must stand on the goal line where the side of the penalty box meets it and
- decide whether the goalkeeper moved off the goal line before the penalty-taker kicked the ball.
- decide whether the ball crossed the goal line.
- Entering the Field of Play
Linesmen rarely enter the field of play, remaining on the sideline for most of the game. If needed, a linesman can enter the field of play to assist the referee during free-kick procedures, specifically to help enforce the 10 yards law. Linesmen also help the referee when scuffles or fights occur. According to the FIFA Laws of the Game, the nearest assistant referee may enter the field of play to assist the referee in situations of mass confrontation..
- Holding the Flag
When you aren’t using the flag, keep it down and on pitch-side of your body so the ref can see it at all times. Especially don’t wave it about unless you want the refs attention.
