I was thinking of this
[LAWS](f)
The 10-metre Law does not apply when a player kicks the ball, and an opponent charges down the kick, and a team-mate of the kicker who was in front of the imaginary 10-metre line across the field then plays the ball. The opponent was not 'waiting to play the ball' and the team-mate is onside. The 10-metre Law applies if the ball touches or is played by an opponent but is not charged down.[/LAWS]
but misrembering it, as it doesn't apply technically. But maybe it should
