It's not a penalty or a foul, but it's a stoppage of play, like offsides.\n\nWhen you have the puck behind the red line (your half of the ice), and you shoot it to the other side of the rink (behind the goal line), and the other team is the first to touch the puck (USA rules, in Olympics you didn't need to touch the puck), then play stops, and there is a faceoff back in your zone.\n\nA new rule this year in USA hockey was if you iced the puck, you can't substitute any players.
