Normally, penalty calls are made by the referees. Linesmen are left to handle icing and offside violations. They can also stop play for a number of reasons, including hand passes, pucks played with a high stick, injuries, and a handful of other situations.
They can stop play for situations where there are too many men on the ice, when objects are thrown on the ice from the bench or penalty box, or when a player receives a stick illegally. In those cases, the linesman will report the issue to the referee, who makes the call.
They can also report major penalties, game misconducts, abuse of officials, and unsportsmanlike conduct penalties at the next stoppage in play. You may recall newly-acquired Ryan Johansen picking up a penalty for unsportsmanlike conduct after getting tossed from the faceoff circle by linesman Greg Devorski.

Philadelphia Flyers defenseman Radko Gudas also found himself on the wrong end of a linesman’s penalty call. After a low hit appeared to injureLucas Lessio of the Montreal Canadiens, linesman Greg Devorskiblew the whistle. During the stoppage he conferred with referees Steve Kozari and Kyle Rehman, who ultimately ended Gudas’s night early with a five-minute major for clipping and a mandatory game misconduct.
