In
ice hockey, play is said to be offside if a player on the attacking team enters the attacking zone before the
puck itself enters the zone, whether it is being carried by a teammate or otherwise sent in across the blue line. When an offside violation occurs, the
linesman blows the play dead, and a
faceoff is conducted in the neutral zone closest to where the offside was.
