"You want to win the hockey game," Jagr said. "The best thing is to put this behind us, and the whole team can now be concerned about winning. ... I've learned that hockey is a team game. Only team victories count. I wish it had happened in the first period, or it was a goal to give us the lead."
Florida interim coach Tom Rowe says he understands Jagr's team-first mentality.
"(Jagr's) upset. He's second in history in NHL scoring and he doesn't even care about that right now," Rowe said. "The two points were more important to him."
Jagr got point No. 1,888 with an assist with 6:40 left to break the tie with Messier.
"I appreciate everything ... over my hockey career, and I thank the fans," Jagr said in a brief ceremony during which he was given a golden stick.
Only Wayne Gretzky, with 2,857 points, has more than Jagr. Aleksander Barkov was credited with the goal that deflected off the 44-year-old Czech star.
In a video, Gretzky offered congratulations. "You play the game the right way," he told Jagr.
The game was stopped for a celebration, and Jagr came onto the ice to accept the commemorative golden stick from the Panthers. He waved to the crowd, got congratulatory stick-taps from both teams, and the game -- his 1,663rd in the NHL -- resumed.
The Bruins, whom Jagr played 22 games for in 2013, were fine with the brief stoppage of play to honor No. 68.
"He deserves that attention. We didn't mind that at all," Boston coach Claude Julien said. "He played for us so it was nice to be a part of it."
Frank Vatrano, Patrice Bergeron and David Backes scored for Boston, and Tuukka Rask made 29 saves.
Rask improved to 18-3-1 against Florida, and Boston is 16-2-1 in its past 19 games against the Panthers.
Rask was thrilled to have been a part of a night that not only included the win but also Jagr's historic achievement.
"You don't get to be (on the ice) with that kind of a legend very often so it was great to see that," Rask said. "I'm very happy for him; it's great."
Vatrano, called up this week from Providence of the AHL, scored in his first game and on his second shot as a Bruin on a wrister from the slot at 2:09 of the second period.
"You aren't a part of something like that every day," Vatrano said about Jagr's memorable assist. "He's a tremendous player, one of the best in the game and it's awesome."
