[In-goal] Warming up players in-goal


, Advises in England
Was it a PK or a conversion? If the former, then "the opposing team" must stand still; this has to include those in the playing area. if the latter, the restriction is on charging across the GL before the kicker advances on the ball.
Unfortunately I don't remember, but it was still a case of the opposition having too many players in the playing area.
