In case you forgot to read the memo the NHL plans to enforce stiffer penalties to players involved in hit-to-the-head incidents.

League disciplinarian Colin Campell circulated a memo to all 30 clubs indicating that suspension length will increase if the recent trend persists.

"We can not and will not tolerate blows to the head that are deliberate, avoidable and illegal," the memo states.

In the past week two players were suspended in separate incidents. Ottawa forward Jarkko Ruutu served two games for an elbow to the head of Montreal forward Maxime Lapierre while Long Island rookie Thomas Pock will serve five games for a deliberate shot to Ottawa call up Ryan Shannon.

Complete text of NHL memo:

"Recently, we have had two (2) supplemental discipline incidents involving direct elbow blows to the head. This is a play that we have been trying to remove from our game for a number of years. In one case there was no injury and in the other incident the elbowed player received a concussion. Both players delivering the elbows had never before been involved in supplemental discipline.

"We cannot and will not tolerate blows to the head that are deliberate, avoidable and illegal. Furthermore, both the history and status of the offender (first time versus repeat) and the nature of the injury caused (if any) will be taken into consideration as they have been in the past. The length of suspensions for illegal blows to the head will be increased if these incidents persist across the League. Taking steps to maintain the safest on-ice environment possible for the players remains our most important priority."
