The goal was his first since Feb. 18th at San Jose.

"Anytime you reach a milestone it's special," Chara said. "I'm not one of those guys that's going to score another 100. It's a pretty decent number for a guy who wasn't supposed to play the game. It's a big win for us to clinch the playoffs."

Patrice Bergeron, David Pastrnak and Brad Marchand also had a goal and an assist, and Steve Kampfer, Karson Kuhlman and Noel Acciari had the other goals for Boston. Danton Heinen had two assists and Jaroslav Halak stopped 31 shots and also had an assist as the Bruins won their fourth straight.

Chara is in his 13th season with Boston and 21st in the NHL. He is the second-oldest active NHL player, behind Pittsburgh's Matt Cullen.

"I don't care how long you played. It feels good to score a goal," coach Bruce Cassidy said. "We're all happy for Z."

Vincent Trocheck, Mike Hoffman and Jayce Hawryluk scored for the Panthers, and Sam Montembeault finished with 32 saves.

Kampfer and Pastrnak scored 48 seconds apart to stretch the Bruins' lead to 6-2 with 3:24 to go in the middle period.

"We beat ourselves, 24 turnovers, and their first four goals came off our sticks on turnovers," Panthers coach Bob Boughner said. "It was stupidity and bad turnovers that ended up in the back of our net."

Trocheck scored a power-play goal at 3:57 of the third to get the Panthers within three.

Bergeron's empty-netter with 26.8 left capped the scoring.

"It's one of those things where we know we have to be better and we know that's not good enough especially against good teams," Panthers defenseman Keith Yandle said.

Florida's Aleksander Barkov landed face down on the ice after a collision with Chara with 3:04 left in the game but left under his own power.
