a designated player must serve out that segment of the penalty in the box (similar to the above-mentioned "two-and-ten"). In some rare cases, a player may receive up to nineteen minutes in penalties for one string of plays. This could involve receiving a four-minute double minor penalty, getting in a fight with an opposing player who retaliates, and then receiving a game misconduct after the fight. In this case, the player is ejected and two teammates must serve the double-minor and major penalties. A player who is tripped, or illegally obstructed in some way, by an opponent on a breakaway – when there are no defenders except the goaltender between him and the opponent's goal – is awarded a penalty shot, an attempt to score without opposition from any defenders except the goaltender. A penalty shot is also awarded for a defender other than the goaltender covering the puck in the goal crease, a goaltender intentionally displacing his own goal posts during a breakaway to avoid a goal, a defender intentionally displacing his own goal posts when there is less than two minutes to play in regulation time or at any point during overtime, or a player or coach intentionally throwing a stick or other object at the puck or the puck carrier and the throwing action disrupts a shot or pass play. Officials also stop play for puck movement violations, such as using one's hands to pass the puck in the offensive end, but no players are penalized for these offenses. The sole exceptions are deliberately falling on or gathering the puck to the body, carrying the puck in the hand, and shooting the puck out of play in one's defensive zone (all penalized two minutes for delay of game). Officials A typical game of inline hockey has two officials on the floor, charged with enforcing the rules of the game. There are typically two referees who call goals and penalties. Due to not having offside and icing violations, there usually are no linesmen used. On-ice officials are assisted by off-ice officials who act as time keepers, and official scorers. Officials are selected by the league for which they work. Amateur hockey leagues use guidelines established by national organizing bodies as a basis for choosing their officiating staffs. In North America, the national organizing bodies USA Roller Sports and Canada Inline approve officials according to their experience level as
