Game 5 is Tuesday in Montreal.

Montreal finally broke through on its power play receiving a goal from Subban two minutes into the third period. Subban had gone five games in the playoffs without a goal before his slap shot from the center blue line tied it at 2.

The Rangers forged ahead 2-1 late in the second period.
New York goaltender Henrik Lundqvist, who made 27 saves in the game, sent a clearing pass around the boards to defenseman Dan Girardi, who threaded a two-line pass right on Brassard's stick. The Rangers forward blasted a slap shot from 20 feet out for his fifth goal of the playoffs at 19:04.
The Canadiens tied it at 1 on an even strength goal from Bouillon at 8:08 of the second period. He fired a snap shot over Lundqvist's left shoulder for his second goal of the post-season. Bouillon was making his first appearance for Montreal since Game 2 of the conference semifinals against Boston.

With forward Benoit Pouliot serving a high sticking penalty, Hagelin received a head-on pass from center Brian Boyle from inside the New York blue line.
