In a soccer match, the assistant referee, also known as a linesman, uses a variety of flag signals to communicate with the referee and players during the game. These signals are used to indicate various aspects of the game, including offside, fouls, throw-in, and corner kicks.
Here are some common flag signals used by assistant referees in soccer:
When a player is in an offside position, the assistant referee raises the flag straight up in the air. This indicates that the player is offside and the play should be stopped.
When a foul has occurred, the assistant referee will raise the flag diagonally across the chest. This indicates to the referee that a foul has occurred and the play should be stopped.
When the ball goes out of bounds and a throw-in is awarded to a team, the assistant referee will point the flag in the direction of the team that is awarded the throw-in.
When the ball goes out of bounds and a corner kick is awarded to a team, the assistant referee will point the flag towards the corner flag on the side of the team that is awarded the corner kick.
When the ball goes out of bounds over the end line and a goal kick is awarded to a team, the assistant referee will point the flag toward the corner flag on the side of the team that is awarded the goal kick.
When a player is being substituted, the assistant referee will hold the flag in a horizontal position across the waist to indicate that a substitution is taking place.
The flag signal from assistant referees is a great help to make accurate calls in the match. However, the main referee has the final say in all decisions on the field. Besides flag signals, the assistant referee also uses referee headsets to confirm it again to the main referee to make sure there are no missing calls in the match.
