Ference signed for four years and reportedly US$13 million, a hefty raise from his last contract with the Boston Bruins. He would count $3.25 million against the salary cap.
The 34-year-old Edmonton native was a key part of the Bruins' run to the Stanley Cup final, though there was no room for him to return to Boston because of salary-cap issues and plenty of young defencemen coming up through the ranks.
In 760 career NHL games, Ference has 37 goals and 156 assists. He was a part of the Bruins' Cup-champion team in 2011.
