What's the penalty for fighting in an adult game?

Question

Accepted Answer

A punch or attempted punch toward an opponent counts as fighting, whether or not it lands.

Situation	Penalty
Fighting	Major plus game misconduct, which also means a next-game suspension
Starting or instigating the fight	An additional minor
Retaliating after being struck	Minor, double minor, or major plus game misconduct (referee's call)
Being struck and not retaliating	No fighting penalty
First player to join a fight already in progress	Game misconduct
Dropping gloves or stick to join an altercation you weren't in	Minor (plus a game misconduct if you instigate the next one)
Deliberately removing your own helmet before a fight, or an opponent's	Match penalty
Fighting off the ice, before, during or after the game	Major plus game misconduct

Repeat offenders: a second fighting major with the same team in the same season brings a three-game suspension. A third means suspension until a hearing.
