when a player shoots the puck from behind his red line down the ice and goes over the opposing team’s red line (without anyone touching it in between).
so the puck has to go over the 2 red lines in order for it to be icing. Unless it goes into the opposing team’s net, the goal will count.
when there is an icing call, the puck is brought back to the defenders zone (of the team that committed the infraction) for a faceoff.
