The Stanley Cup finalist Boston Bruins and Dallas Stars completed a seven-player trade on Thursday just ahead of the opening of the free agent market.
Boston sent forwards Rich Peverley, Tyler Seguin and defenseman Ryan Button to Dallas in exchange for forward Loui Eriksson and prospects Matt Fraser, Reilly Smith and defenseman Joe Morrow.
The key to the deal for Boston was Eriksson, a native of Sweden who appeared in all 48 regular season games for the Stars and tied for the team lead with 12 goals.
Eriksson has spent his entire seven-year career in Dallas, scoring 150 goals and 357 points.
The second overall pick in the 2010 draft, Seguin had 56 goals and 65 assists in three seasons in Boston.
He helped the Bruins to a Stanley Cup title in 2011 and appeared in all 22 playoff games this season as Boston fell just short of a second championship in three years, losing the final to the Chicago Blackhawks.
Peverley was also a member of the Bruins' 2011 Stanley Cup team and this season had six goals and 12 assists in 47 regular season games.
The Bruins and Stars made the moves with what is expected to be a very active National Hockey League free agent market, set to open on Friday.
