from Kerry Fraser of TSN,

Given the climate within the game that has evolved over the past number of seasons there is heightened awareness and sensitivity to player safety issues. Ongoing studies conducted by both NHL and independent medical experts provide scientific evidence and newfound knowledge that is slowly changing attitudes and redefining acceptable practices and behavior.

This is being addressed in part, with the addition of new rules relative to protective equipment. Last season visors became mandatory for any player with fewer than 25 games of NHL experience (rule 9.7). In addition, no player is allowed to remove his helmet prior to engaging in a fight. If he does so, a minor penalty for unsportsmanlike conduct will be assessed under rule 46.6.

You witnessed a continuation of the player safety theme on Tuesday night when Linesmen Scott Driscoll and Greg Devorski demonstrated their good judgment and quick response to intervene in an altercation before it escalated to full-blown fisticuffs.
