The Canadiens announced that Subban had suffered a minor neck injury after leaving Montreal General Hospital late Thursday. He tweeted on Friday that was doing better.
Feeling good, and feeling the love. Thanks for all the support!!

The incident overshadowed Montreal's 3-2 victory over the Buffalo Sabres.
Subban was injured late in the third period when teammate Alexei Emelin ran into him, knocking him on the side of the head with his backside while retrieving the puck in Montreal's corner. The 2013 Norris Trophy winner was nearly motionless on the ice for about 10 minutes while doctors and trainers tended to him.
"It's scary to see that many trainers and doctors on the ice," said captain Max Pacioretty, who added Subban was communicating with him shortly after the accident. "Nobody knew exactly what happened. That was the scariest part for me. It looked like a nothing play. It was impossible to concentrate after that."
Coach Michel Therrien said Subban will undergo treatment and won't be available for the game against Minnesota on Saturday, ending his streak of 273 consecutive regular-season games.
Subban, who leads the Canadiens in points (50) and assists (44), was presented the Jean Beliveau Trophy before Thursday's game for his community involvement.
"You're trying to win a hockey game, but you almost felt like you don't want to keep playing at that point in time," Sabres coach Dan Bylsma said. "The game's an afterthought."
"I've been in that position before, and it brings back a lot of tough memories," said Pacioretty, who was taken off the Bell Centre ice on a stretcher almost exactly five years ago after he suffered a severe concussion and a fractured vertebra as a result of a check by Boston's Zdeno Chara. "It was really hard to watch."
Therrien said a defenseman and a forward would be recalled from the St. John's IceCaps of the AHL on Friday to fill out his injury-riddled roster.
