After 16 NHL seasons, a Conn Smythe Trophy and a Stanley Cup championship, former Colorado Avalanche goaltender Jean-Sebastien Giguere is calling it a career.

Giguere announced Thursday he is retiring from the NHL, ending a career that saw him win 262 games in 597 regular-season contests. He made the announcement in Quebec with the Blainville-Boisbriand Armada hockey team, where he is a part owner of the Quebec Major Junior Hockey League franchise.

The Montreal native spent most of the last three seasons in a backup role for the Avalanche and helped in the development of goalie Semyon Varlamov.

When Varlamov needed a night off, Giguere proved he was still a capable NHL netminder and could give the Avalanche a chance to win every game. He appeared in 72 games with Colorado and had a 31-21-8 record, four shutouts, a 2.51 goals-against average and .914 save percentage.

"That's the job of a backup. You have to be ready for all kinds of scenarios," Giguere said in October to "Sometimes a goalie might get sick, sometimes he might get hurt in warm-up. Sometimes he might be out for a month, and the team isn't necessarily going to get a trade. You have to be ready physically and mentally for those kinds of challenges."

It was a healthy competition in net between Giguere and Varlamov, with each goalie pushing the other to be better while also forming a friendship. The goalie tandem excelled together at the start of last season and shared the NHL's Second Star of the week honors for the week ending Oct. 13.
