Offside (ice hockey)

"In ice hockey, a play is offside if a player on the attacking team enters the offensive zone before the puck, unless the puck is sent or carried there by a defending player. When an offside violation occurs, a linesman will stop play. A faceoff is then held at a neutral ice spot closest to the infraction to restart play. ...
The National Hockey League (NHL) and International Ice Hockey Federation (IIHF) apply similar rules for determining offside. A player is judged to be offside if their skates completely cross the blue line dividing their offensive zone from the neutral zone before the puck completely crosses the same line. In both organizations, it is the position of a player's skates that are important. They cannot use their stick or other part of their body to remain onside. The lone caveat to this rule is that an attacking player's skates may precede the puck into the attacking zone when they are skating backwards and if they are in control of the puck."

"A penalty in ice hockey is a punishment for an infringement of the rules. Most penalties are enforced by detaining the offending player within a penalty box for a set number of minutes, during which the player can not participate in play. Penalties are called and enforced by the referee, or in some cases the linesmen. The offending team usually may not replace the player on the ice, leaving them short handed as opposed to full strength. The opposing team is said to be on a power play, having one player more on the ice than the short-handed team. The short handed team is said to be "penalty killing" until the penalty expires and the penalized player returns to play. While standards vary somewhat between leagues, most leagues recognize several common degrees of penalty, as well as common infractions." [Penalty (ice hockey). Wikipedia]
