63.6 Awarded Goal - In the event that the goal post is displaced, either
deliberately or accidentally, by a defending player, prior to the puck
crossing the goal line between the normal position of the goalposts,
the Referee may award a goal.
In order to award a goal in this situation, the goal post must have
been displaced by the actions of a defending player, the puck must
have been shot (or the player must be in the act of shooting) at the
goal prior to the goal post being displaced, and it must be determined
that the puck would have entered the net between the normal position
of the goal posts.
When the goal post has been displaced deliberately by the
defending team when their goalkeeper has been removed for an extra
attacker thereby preventing an impending goal by the attacking team,
the Referee shall award a goal to the attacking team.
The goal frame is considered to be displaced if either or both goal
pegs are no longer in their respective holes in the ice, or the net has
come completely off one or both pegs, prior to or as the puck enters the goal.
