When you see an off-side infraction:
- blow the whistle
- point to the face-off location—the face-off always takes place closest to the point from which the pass originated
- However, if the play is on-side, but a close play, the Linesman will give the wash out signal
When you determine that there’s been a Delayed Off-Side, as the Linesman you:
- raise the non-whistle hand above his head immediately
- Shout, “Off-side”
For more detailed information on face-off locations after an off-side, see Referee Case Book Rule 10.2.
