The game between the Maple Leafs and Washington Capitals featured a huge brawl and a few players being thrown to the ice during the first period.
The Leafs have since apologized for what happened.
Here’s what you need to know.
The NHL announced on Thursday night that its “Game Night” promotion would not run for the entire game on Thursday.
The game had been postponed indefinitely, with the NHL saying that “game night activities are the focus of this year’s season.”
The NHL said it was aware of the incident and that players were being treated for minor injuries.
The NHL also said that it would “review the incident.”
It added that it will not be able to offer refunds for players and their families.
The incident has not been officially reported.
Who was involved?
The fight happened after a penalty shot by the Capitals had failed to get past Leafs defenceman Nikita Kucherov in the first.
Leafs winger James van Riemsdyk got in Kuckeyv’s face, and the Capitals were penalized after he hit Kucherevs’ head.
That caused a brawl that eventually broke out in the ice.
The two players continued to fight in the second period, and a third fight broke out between Leafs defencemen James van der Sar and Joffrey Lupul in the crease.
Lupul got up to throw punches at van der Saars’ head, and van der Sakas kicked him in the head and threw him to the ground.
The players then began to hit each other with sticks and gloves, which resulted in more fighting.
Lupu said he was hit in the eye and ribs.
Lupus and van den Sar were both assessed five minor penalties for roughing, and Lupul received a game misconduct.
What did the league say?
The league issued a statement Thursday saying that the league would review the incident.
“We deeply regret any distress that may have been caused by this incident, and we have made clear to all involved that this type of behaviour will not occur in the future,” the statement read.
The league said that the NHL would work with the players’ union, the NHLPA, and local authorities to “develop a safe environment for players, coaches and trainers in future games.”
“We are committed to helping players and coaches in any way we can, and our thoughts and prayers are with the families of those who have been injured,” the league said.
What should players do?
Players should stay away from the scene and take precautions, such as not going into the ice, staying in the tunnel, not bringing any equipment, and wearing their helmets.
What’s the timeline?
The incident took place on Friday night at the Pepsi Center, a venue that was packed for the NHL’s Winter Classic between the Pittsburgh Penguins and Chicago Blackhawks.
The Penguins defeated the Blackhawks 3-2.
The Capitals won 4-1.
The Maple Leafs defeated the Flyers 4-0.
