BOSTON (CBS) – The Boston Bruins are looking to deal the rights to defenseman Tomas Kaberle, according to a tweet by TSN’s Darren Drager.

The Bruins sent out a league-wide email Tuesday informing teams they would like to try to move the rights to the upcoming free agent. Acquiring his rights would give the team exclusive negotiation rights with Kaberle when free agency begins on Friday.

The 33-year-old Kaberle was acquired from the Toronto Maple Leafs at the trade deadline for Joe Colborne, the Bruins 2011 first-round pick and a 2012 second-round pick. He was widely criticized during his time in Boston, recorded one goal and just eight assists in 24 regular season games. He was tied for second on the team with 11 assists in the playoffs.
