The Boston Bruins have traded defenceman Dougie Hamilton to the Calgary Flames.

TSN Hockey Insider Darren Dreger reports the haul for Hamilton is not yet known, however it will include Calgary’s 15th overall pick in Friday night’s NHL Draft, along with other selections.

Hamilton, a restricted free agent, scored 10 goals and tallied 32 assists in 72 games with the Bruins last season.

The 22-year-old, who was selected ninth overall in the 2011 NHL Draft by the Bruins, made his NHL debut in the 2012-13 season. He has 22 goals and 61 assists in 178 career games, all with the Bruins. He owns a career plus-23 rating, despite finishing minus-3 last season.

The Bruins selected Hamilton with the second first-round pick acquired in the blockbuster trade of Phil Kessel to the Toronto Maple Leafs in 2009. The other first round pick, used in the 2010 NHL draft, saw Tyler Seguin selected by the Bruins. Seguin was traded to the Dallas Stars in 2013.

Dreger adds the Flames should not have trouble extending Hamilton due to familiarity.
