During the final hour prior to the NHL's trade deadline, GM Peter Chiarelli reeled in veteran blueliner Andrej Meszaros from Philly.
Boston sent a third-round pick the Flyers in the deal, which Sportsnet's Dan Murphy first reported.
A 28-year-old veteran of 571 regular-season games, Meszaros has been in Philadelphia since being traded there from Tampa on July 1, 2010. Often a healthy scratch on the Flyers' back end this season, the 6-foot-2 rearguard had 5-12-17 totals through 38 games and a plus-1 rating. He averaged 17:22 of ice time, which is the lowest of his nine-season career in the NHL.
As a rookie in 2005-06 in Ottawa, when he had a career-best 39 points in 82 contests, Meszaros was teammates with Zdeno Chara. The two have represented Slovakia in the last three Olympics. He averaged just under 19 minutes per game in Sochi and had an even plus-minus rating.
Meszaros didn't see a lot of time on special teams for the Flyers this season, averaging 0:51 of shorthanded time per game (sixth among Philly blueliners) and 1:02 a game on the man advantage. He played a bigger role in 2012-13 under previous head coach Peter Laviolette (1:18 SH, 2:02 PP).
Philadelphia acquired Andrew MacDonald from the Islanders on Tuesday, paving the way for Meszaros' departure. Boston claimed Corey Potter off waivers from Edmonton earlier in the day.
Meszaros, a left-shooting blueliner, is in the final season of a six-year, $24 million deal.
