Alberts traded to Philly for Lukacevic and pick
The Bruins traded D Andrew Alberts to the Philadelphia Flyers for Ned Luckacevic and a conditional 4th round draft pick (turns into a 3rd if he re-signs).
This means that Lashoff could be called up for the 6th/7th defensive spot with Hnidy seeing more playing time. This was mostly a cap cutting cost, shedding 1.25 million off the cap, a substantial amount. This gives the Bruins a lot more flexibility regarding trades and call-ups.
Luckacevic is a prospect who will see a lot of time in Providence. He has never played in the NHL. The 4th round pick basically replaces the pick sent to Minnesota in the Manny Fernandez deal.
