The Bruins have acquired defenseman Wade Redden from the St. Louis Blues in exchange for a late round draft pick in the 2014 draft, according to a hockey source.

Redden was a former teammate of Bruins captain Zdeno Chara and third-line center Chris Kelly, but he will be serving strictly as a depth defenseman for the Bruins as they work toward a Stanley Cup. He’ll be insurance in case injuries or ineffectiveness gnaw away at Boston’s back line during the Stanley Cup playoff gauntlet.

"Both (Zdeno) Chara and (Chris) Kelly were great teammates," Redden said. "Excited to join them and the (Bruins) team."

Redden has five points (2 goals, 3 assists) in 23 games for the St. Louis Blues this season while registering a minus-11 after getting rescued from AHL jail when he was bought out of his exorbitant contract with the New York Rangers. A six year, $39 million deal and certain CBA restrictions in the last labor agreement had kept Redden saddled in the AHL over the last two seasons for the Connecticut Whale.

Redden has accumulated over 400 points in 1,017 career NHL games, and was the defensemen Ottawa famously chose to stick with when they lost Zdeno Chara to free agency when both players were skating on the back line for the Senators.

There were whispers in the last 24 hours that Phoenix defensemen Derek Morris could possibly be dealt back to Boston after he was traded away three seasons ago, but obviously that deal never materialized before the deadline.
