BOSTON (AP) — It's the 34th time the Montreal Canadiens and Boston Bruins are meeting in the postseason. For just the sixth time, it required multiple overtimes to decide a game as P.K. Subban scored a power-play goal at 4:17 of the second overtime to give the Canadiens a heart-stopping 4-3 victory in Game 1.

It was Subban's second power-play goal of the game. Boston forced overtime by scoring three times in the third period before losing in the second overtime. Boston fans pelted the ice with cups and giveaway towels as the players filed off of the ice.

Carey Price was magnificent in goal for Montreal, turning back 48 shots. Montreal is a perfect 5-0 in the postseason. Game 2 is Saturday, also in Boston.

Tonight, two more conference semifinals get underway. The New York Rangers are at Pittsburgh and the Minnesota Wild take on the defending Stanley Cup champion Chicago Blackhawks.

VANCOUVER, British Columbia (AP) — The Vancouver Canucks have fired John Tortorella one year into a long-term deal. He signed a five-year contract last summer after being dismissed by the New York Rangers. The Canucks finished 25th in the 30-team NHL this season for their worst finish in 14 years. Assistant coach Mike Sullivan was also fired.

UNIONDALE, N.Y. (AP) — Washington has sent the negotiating rights of veteran goalie Jaroslav Halak (YAHR'-oh-slav HA'-lak) to the Islanders for a fourth-round draft pick. Halak split this season between St. Louis and Washington and went a combined 29-13-13 in 52 games. He was traded by the Blues to Buffalo on March 1 but was sent to the Caps four days later before playing a game for the Sabres.
