The Kings have acquired seven-time 20-goal scorer forward Marco Sturm from the Bruins in exchange for future considerations, Kings President/GM Dean Lombardi announced today. The trade is subject to Sturm passing a physical. Sturm, 32, spent the last five seasons with the Bruins where he compiled 193 points, 156 penalty minutes and a plus-24 rating, while serving as a club alternate captain.

In 855 career NHL games with the Bruins and Sharks, Sturm has accumulated 466 points (234-232=466), 398 penalty minutes and a plus-66 rating. Sturm was originally drafted by San Jose in the first round (21st overall) in the 1996 NHL Entry Draft (by then-Sharks GM Lombardi).

His four goals rank fourth among all Bruins skaters, while his 19 penalty minutes rank sixth. A native of Calgary, Alberta, Nelson has played in 118 career AHL games, all with Providence, notching 14 goals and 27 points. His best season came in 2009-10 when he registered AHL career-highs with eight goals, five assists and 13 points in 44 games. Prior to his first full professional season, Nelson excelled at the junior level during four seasons with the Swift Current Broncos of the WHL. Nelson was originally selected by the Bruins in the sixth round, 158th overall, at the 2006 NHL Entry Draft.
