Reilly Smith and Zdeno Chara scored power-play goals Sunday as the Boston Bruins beat the Detroit Red Wings, 4-1, to tie their playoff series at one game apiece.
Smith scored his first career playoff goal 10 minutes, 35 seconds into the game, a little more than three minutes after Justin Florek's goal gave the host Bruins a 1-0 lead.
The Red Wings managed just one shot on goal on their four power plays.
"I thought we were ineffective, period," Red Wings coach Mike Babcock said. "They were engaged. They won the battles. They were quick. We were slow."
Canadiens 3, Lightning 2 - Tomas Plekanec scored at 5:43 of the third period and Carey Price made 27 saves to give host Montreal a victory over Tampa Bay and a 3-0 lead in their best-of-seven series.
Rene Bourque scored 11 seconds into the game, and Brendan Gallagher broke a 1-1 tie 18:10 into the second period.
Tampa Bay's Steven Stamkos left briefly after taking a knee to the back of the head.
Chicago Blackhawks defenseman Brent Seabrook was suspended for three games for his hit on St. Louis center David Backes during Game 2 of their first-round playoff series.
Seabrook received a five-minute major and game misconduct penalty for a vicious elbow to Backes' head late in the third period. Backes had to be helped off the ice and did not return.
Nathan MacKinnon, 18, scored his first NHL postseason goal and dished out three assists Saturday in a 4-2 win over the visiting Minnesota Wild. The Avalanche lead the series, two games to none.
