According to TSN’s Darren Dreger (via twitter) the Bruins have traded winger Marco Sturm  to the Kings. According to ESPN’s James Murphy, the Bruins received a conditional fifth-round pick.
Sturm is still recovering from a torn ACL and MCL suffered in last year’s playoffs. In trading him and his $3.5 million salary cap hit, the team will be cap-compliant without any issue. The team would have needed to shed salary before Sturm’s return, as they had been given cap relief with both Sturm and Marc Savard  on long-term injury reserve.
The Bruins are now $46,128 under the cap, according to CapGeek .
