Wingers are often found along the boards in the offensive and defensive end of the rink battling for possession of loose pucks. Defensively, a winger tries to disrupt plays by the opposing wings and limit their shot attempts. The referee supervises the game, calls penalties and determines goals. He also handles faceoffs at center ice to start each period. Linesmen - Two linesmen are used during a game.
Linesmen call offside, offside passes, and icing offenses.
Linesmen handle all faceoffs except those at the start of each period. A linesman does not call penalties, but they can recommend to the referee that a penalty be called. Goal Judge - One is positioned at each end of the rink behind each goal. The goal judge indicates when a goal is scored by turning on the red light just above his station. The referee can ask his advice on disputed goals, but the referee is the final word and can overrule the goal judge.
