It’s a two-year contract with an annual salary cap hit of $2.5 million.
Colborne had a career high 19 goals and 25 assists in 73 games for the Calgary Flames last season. He has 106 points in 233 career NHL games split between the Flames and Toronto Maple Leafs. Colborne was selected 16th overall by the Bruins in 2008.
The 26-year-old played two seasons at the University of Denver, so joining Colorado should be a smooth transition for the centre. Colborne was college teammates with Patrick Wiercioch who also signed with the Avs earlier in the day.
