According to a tweet from TSN’s Darren Dreger , the Bruins sent out an email Tuesday offering Tomas Kaberle ‘s negotiating rights to other teams. Any team that acquired Kaberle would, as the Bruins do now, be able to negotiate with the defenseman exclusively leading up to the opening of free agency on Friday.
Kaberle, 33, is one of only two unrestricted free agents from the Bruins’ Stanley Cup  champion lineup. Acquired on Feb. 18 in exchange for center Joe Colborne, a 2011 first-round pick and a 2012 second-rounder, he had one goal and eight assists for nine points in 24 regular-season games with the B’s. He and Dennis Seidenberg  tied for lead among Bruins’ defenseman in postseason points with 11.
Rights to free-agents-to-be can be moved by the teams with which they last played, as the Flyers traded for the rights to goalie Ilya Bryzgalov before locking him up last week. The Canucks traded the rights to defenseman Christian Ehrhoff to the Islanders on Tuesday.
