Rule 75 - Premature Substitution 75.1 Premature Substitution - When a goalkeeper leaves the goal area and proceeds to the players’ bench for the purpose of substituting another player, an on-ice official shall be responsible for seeing that the substitution is not illegal because of the premature departure of the substitute from the bench (before the goalkeeper is at the players’ bench and out of the play). If the substitution is made prematurely, an on-ice official shall stop the play immediately by blowing the whistle unless the nonoffending team has possession of the puck, in which event the stoppage shall be delayed until the puck changes hands. A time penalty shall not be assessed against the team making the premature substitution. FACEOFF—Center faceoff spot. When play is stopped with the puck in the offending team’s defensive zone, the faceoff shall be at the nearest end zone faceoff spot. When play is stopped with the puck in the neutral zone on the offending team’s side of the red line, the faceoff shall take place at the nearest neutral zone faceoff spot.
