Gary Bettman and the NHL announce new rule changes for the upcoming season

"This only will apply to delay of game penalties when the puck is determined to have deflected off a player, stick, glass or boards, and not on a judgment call on how the puck left the defensive zone (e.g., batted pucks or if the puck was shot out from the defensive zone). In the event of a failed challenge, another two-minute minor penalty will be assessed (in addition to the existing delay of game penalty)."

"There will be an adjustment to Rule 63.8 so that the defensive team cannot make a line change in the event its goaltender accidentally dislodges the net (old language applied just to skater).

Following an icing, the offensive center also now will receive one warning (same as the defensive player) for a face-off violation."

"The referee now will provide the offending team (coach and players) with one warning regarding players sitting on the boards (and will so advise the other team). After one warning in a game, the team precipitating the warning will be issued a bench minor penalty for future violations."
