The Nashville Predators added depth on their blue line on Friday, acquiring veteran defenseman Hal Gill from the Montreal Canadiens.

The Predators also receive a conditional 2013 fifth-round pick, in exchange for forwards Blake Geoffrion and Robert Slaney, plus a 2012 second-round pick.

“Hal Gill brings our team a number of elements — size, penalty-killing ability, depth on defense and playoff experience,” said Predators General Manager David Poile. “He has won a Stanley Cup and played a combined 69 playoff games over the last four years, experience that significantly benefits our team.”

In 14 seasons, Gill has 36 goals and 143 assists in 1,047 regular-season games with the Bruins, Maple Leafs, Penguins and Canadiens, and also has 105 games of playoff experience, including back-to-back Stanley Cup Final appearances with the Pittsburgh Penguins in 2008 and 2009. He was part of the Pens’ top shut-down pairing in 2009 when the Penguins won the Stanley Cup.

Gill can become an unrestricted free agent if not signed by July 1.

In 22 NHL games this season, Geoffrion has three assists, but hasn’t played in the League since December 26, 2011. In 20 AHL games, the 6-foot-1, 190-pound left wing has two goals and seven assists.

Slaney, a 6-2, 203-pound left wing, has split the season between the AHL and the ECHL Cincinnati Cyclones. He had one assist in nine AHL games, and eight goals and five assists in 23 ECHL games.
