The Bruins have acquired Chris Bourque, son of legendary defenseman Ray Bourque, from the Capitals for Zach Hamill.

Chris Bourque most recently played for Hershey, Washington's AHL affiliate. Bourque is a fringe NHLer who has appeared in 33 big-league games between Washington and Pittsburgh. Bourque played one year of college hockey at Boston University.

Bourque could be in the mix for a fourth-line energy role if he has a good training camp.

Hamill was the Bruins' first-round pick in 2007. Hamill would have been a restricted free agent on July 1. It's possible the Bruins might not have tendered Hamill, making him an unrestricted free agent.
