NHL GM's will recommend a rule change on blindside hits to the head, looking to protect players and punish those responsible, according to an Associated Press report. The unanimous decision Wednesday came at the end of three days of meetings in which player head injuries was the predominant issue. The GMs will recommend to the competition committee that referees call a minor or major penalty for any hit where the primary point of contact is the head. Such a violation would be reviewed for possibly further discipline.
