The Boston Bruins hired former Colorado Avalanche head coach Joe Sacco as an assistant coach, the team announced Thursday.

Sacco, 45, spent the 2013-14 season as an assistant coach for the Buffalo Sabres. The former NHL forward served as the head coach of the Avalanche from 2009 to 2013 where he compiled a 130-134-40 record.

Sacco served two years as an assistant coach in the American Hockey League for the Lowell Lock Monsters (2004-05) and the Albany River Rats (2006-07) before becoming a head coach for the Lake Erie Monsters (2007-09).

In his playing career, Sacco skated in 738 NHL games in 13 seasons with five teams (Toronto Maple Leafs, Anaheim Mighty Ducks, New York Islanders, Washington Capitals and Philadelphia Flyers). He registered 94 goals and 119 assists for 213 points.

On Thursday, the Bruins also signed defenseman David Warsofsky to a one-year, two-way contract.

Warsofsky’s salary is worth $600,000 at the NHL level.

Warsofsky appeared in six games for Boston during the 2013-14 season, scoring his first NHL goal against the Senators in Ottawa on Dec. 28 and his first NHL assist on Feb. 8 also against the Senators.

Warsofsky skated in 56 regular-season games for Providence last year, registering six goals and 26 assists (fourth on the team) for 32 points with a plus-8 rating. He skated in 12 games during the Providence Bruins playoff campaign, registering two goals and seven assists.

The blueliner has played in a total of 190 games with Providence from 2010-14, accumulating 14 goals and 66 assists for 80 points.

Prior to joining Providence, Warsofsky skated three seasons (2008-11) with Boston University, where he appeared in 113 games, notching 22 goals and 46 assists.

The 5-foot-9, 170-pound native of Marshfield, Mass., was drafted in the fourth round of the 2008 draft by the St. Louis Blues. The Bruins acquired Warsofsky in exchange for Vladimir Sobotka on June 26, 2010.
