Examples:       
OFFSIDE DEFINED
A player is offside when:
  • He is in an offside position
  • At the moment the ball is played by or touches a teammate
  • And is involved in active play.

   (All 3 conditions must be met!)

Classic Offside
OFFSIDE POSITION (OSP)
A player is in an offside position when:
  • Ahead of the ball
  • Ahead of the 2nd last defender (SLD)
  • And not in own half of field

   (OSP is not an offence by itself. )

ACTIVE PLAY (Defined by FIFA)
A player is involved in active play when:
  • Interferes with play (Plays or is touched by the ball)
  • Interferes with an opponent (impedes or prevents an opponent from playing the ball)
  • Gains an advantage (Interferes with play after a rebound)

EXCEPTIONS

A player cannot be offside directly from a goal kick, corner kick, or throw-in.


IMPORTANT REMINDERS
  • Offside position is judged when the ball is played by or touches a teammate, not when the player in the offside position touches the ball.
  • A player must be involved in active play (as defined by FIFA) to be offside.
  • The IFK restart is taken at the point where the player becomes involved in active play, not where he was when he was judged to be in an offside position. (Law changed in 2016)
