Vancouver Canucks coach John Tortorella was suspended for 15 days without pay following his actions in the game against the Calgary Flames.
Following a mass brawl on the ice, Tortorella carried the ill-feelings in to the first intermission where he was caught on camera trying to force his way in to the opponent's locker room.
Tortorella travelled to New York to meet with the NHL on Monday and, following a hearing, was given the suspension that will see him miss six games for the Canucks.
In a statement, NHL Senior Executive Vice President of Hockey Operations Colin Campbell said: "Mr. Tortorella's actions in attempting to enter the Calgary Flames locker room after the first period were both dangerous and an embarrassment to the League.
"Coaches in the NHL bear the responsibility of providing leadership, even when emotions run high, and Mr. Tortorella failed in his responsibility to the game."
The suspension prevents Tortorella from having any contact with his Canucks team prior to, during or after games.
"We respect the decision made by the National Hockey League today to suspend John Tortorella for 15 days from Sunday, with no contact with the team for six games," GM Mike Gillis said in the Canucks' statement. "We would also like to acknowledge our organization's full support for John and we look forward to having him back behind the bench soon."
Coaching duties will now fall to assistants Mike Sullivan and Glen Gulutzan.
Gulutzan was head coach of the Dallas Stars last season.
Flames coach Bob Hartley was fined $25,000 for his role in the events.
