Former Chicago Blackhawks’ defenseman Duncan Keith announced his retirement Tuesday, at times fighting back tears during a news conference as he thanked teammates, coaches and family members for helping him along the way of his Hall of Fame-caliber career.

Keith will turn 39 on Saturday, and said there’s a noticeable change in how he’s felt in recent postseasons. That, coupled with the desire to spend more time with his son Colton, helped him reach a difficult decision.

In his final season, he put up 21 points (one goal, 20 assists) over 64 games with an average ice time of nearly 20 minutes. He added a goal and four assists in 16 playoff outings as the Oilers made it to the Western Conference final for the first time since advancing to the Stanley Cup series in 2006.

Keith was selected by Chicago in the second round, 54th overall, in the 2002 NHL draft. Keith went on to anchor a Blackhawks blue-line that won the Cup in 2010, 2013 and 2015. He was awarded the Conn Smythe Trophy as playoff MVP in 2015 after piling up 21 points (three goals, 18 assists) in 23 games and won Norris Trophy as top defenseman in 2010 and 2014.

Keith thanked many of the teammates he found success with in Chicago — Jonathan Toews, Patrick Kane and Patrick Sharp — but had special praise for longtime defense partner Brent Seabrook. Keith and Seabrook played their 1,000th game together on Dec. 11, 2018.

Keith said the opportunity to play with Edmonton superstars Connor McDavid and Leon Draisaitl “speaks for itself” and called them “the two best players in the world.”

Keith finished his career with 106 goals, 540 assists and 675 penalty minutes over 1,256 games.

Internationally, Keith helped Canada win Olympic gold at the 2010 and 2014 Winter Games.
