Barch and Gallant dropped the gloves three times last night, each earning an automatic game misconduct after the third.

Special attention will be paid to round two. Gallant, a rookie, must wear a helmet with a visor (new rule). Generally a player who has a moment before and wears a visor will remove his helmet, and the other player will follow suit. However, starting this season players that remove their own helmet before a fight will receive a minor penalty (another new rule). A few sets of players have already picked up the minors, elongating their five PIMs to seven.

Gallant had another idea. He loosened his helmet and invited Barch to do the same. Barch almost took off his own helmet, hesitated, then took off Gallant's instead, and Gallant returned the favor. Then, the fight.

Victorian era honor. The Code. A ridiculous loophole on display. Call it what you will, but the NHL will likely modify the rule to prevent this. The preseason has more players fighting to prove themselves than the regular season though, and it's unlikely we'd see this in a real game setting. Crafty nonetheless.

more plus of course videos of all three fights... You can also watch round two below....

Shawn Thornton mentioned a few days ago he would remove the opponent's helmet if he was wearing a visor and it appears other 'fighters' have caught on quickly.
