The National Hockey League's Department of Player Safety on Saturday unveiled its "Goaltender Interference" video, the second in a series of educational videos designed to help players and fans better understand how specific infractions are viewed and evaluated, what is legal and what merits the assessment of Supplemental Discipline.

This latest video takes viewers through the dynamics of determining the issues involving goaltender interference that can merit the possibility of Supplemental Discipline. It provides several examples of goaltender interference incidents and explains the key components that must be present for a goaltender interference infraction to rise to the level of review by the Department of Player Safety.

On Tuesday, the Department of Player Safety will release an educational video focusing upon Tripping/Slew-Footing. During the course of the season, the department will produce videos focusing upon other types of infractions, as well.

Friday, the Department of Player Safety released its first video, the 'Evolution of a Suspension.' which detailed the multi-step process that the department undergoes any time an incident might require the imposition of supplemental discipline. That video can be viewed here.
