Under IIHF Rules, the following applies:
RULE 73 – PUCK STRIKING AN ON-ICE OFFICIAL
i. Game action will not be stopped because the puck touches an
on-ice official during the regular course of play except when:
- The puck enters the goal net as a result of that contact;
- The puck goes out of play as a result of that contact;
- An on-ice official is injured.
ii. If the attacking team scores a goal because the puck
deflects or bounces directly off an on-ice official, the goal will
not be allowed and the ensuing faceoff will take place at the
nearest faceoff spot to where the puck made contact with the
on-ice official.
iii. If the puck hits an on-ice official and is subsequently put into
the goal net in any legal manner, the goal will be allowed.
iv. If the puck leaves the playing area after hitting an on-ice
official in the neutral zone, the ensuing faceoff will take place at
the faceoff spot in the neutral zone nearest to where the puck made
contact with the on-ice official.
v. If the puck leaves the playing area after hitting an
on-ice official in either end zone, the ensuing faceoff will take
place at the faceoff spot in the end zone nearest to where the
puck made contact with the on-ice official.
Should the interference be intentional, the league will probably take action against the linesman.
