Canadiens win in OT to trim Rangers' lead
Montreal cut New York's series lead to 2-1, and can tie it Sunday night in New York before heading home for Game 5.
Galchenyuk, playing only his second game of these playoffs after returning from an injury Monday, deflected a feed from Tomas Plekanec to win it.
The Rangers tied it with 28.1 seconds left in regulation on Chris Kreider's goal.
New York had its five-game winning streak snapped, and its run of six straight victories over the Canadiens also ended. The Rangers fell to 1-1 in overtime in these playoffs. The Canadiens are 3-1.
Montreal was poised to win it in regulation after Danny Briere scored with 3:02 left in the third, but Kreider matched him when his shot hit the sliding right skate of Canadiens defenseman Alexei Emelin in the crease and caromed past Tokarski, who thrust his head upward in disgust as Madison Square Garden shook.
Tokarski was playing in his second straight game because of a series-ending injury suffered by Price, who was barreled into by Kreider in Game 1.
Briere's goal was also aided by an opposing defenseman, as Ryan McDonagh nudged the puck past goalie Henrik Lundqvist.
Canadiens defenseman Andrei Markov tied it at 1 for the Canadiens in the second period after Carl Hagelin staked New York to the lead in the first.
Tokarski, in his second career playoff game, was sharp throughout. He protected the lead with 55 seconds left, denying Martin St. Louis' drive from the right side with a lunging save, but couldn't close it out then. He stopped 27 shots in a 3-1 loss on Monday in Game 2.
Lundqvist made 22 saves, but couldn't pull out this win.
The Rangers grabbed the lead in the first period that featured only one goal but hardly lacked for action.
By the time Hagelin put New York in front with a batted shot, there had already been one injury as the result of a questionable open-ice hit by Brandon Prust, and an ejection after Dan Carcillo sought revenge on Prust - a former Rangers fan favorite - for his leveling of Derek Stepan.
Loss bugs Quenneville
Blackhawks coach Joel Quenneville is usually a morning person after games. Even losses don't seem quite as bad to him.
Not so much when the sun rose on Thursday, the day after a 6-2 home loss to the Kings in Game 2 of the Western Conference finals.
"I woke up this morning way more angry than I was after the game," he said before the team flew to Los Angeles, where the series continues Saturday tied 1-1. "Normally it's the other way around. Certainly there are a lot of positives to take out of the game. But the little details and the way we gave them the goals (are negatives). Exiting a game like that is a game that should get your attention."
