On 31 May 2012, Lidstrom announced his retirement from the NHL via a press conference with Red Wings Owner Mike Ilitch and General Manager Ken Holland present. The night before, he told the Swedish tabloid Expressen, "I came to the decision last week and I informed our general manager, Ken Holland." Discussing Lidstrom's retirement, former teammate Steve Yzerman described Lidstrom as "one of the all-time best defencemen to ever play." Paul Coffey said, "he was an incredible player" while Chris Chelios said, "There's been guys who are great players, but no one's better than Nick. As good? Yes. But this is as big as it gets. He's one of the best athletes ever and...if you're going to talk about someone who's perfect, Nick's pretty darn close to being perfect." Washington Capitals defenceman John Carlson described Lidstrom as "one of the game's all-time greats on and off the ice." Ken Holland stated his belief that Lidstrom was "the most valuable player of his era."  The following weekend, on 3 June 2012, Lidstrom and his wife took out a full-page ad giving thanks to the city of Detroit for making his family feel at home for the past 21 years. On 8 July 2012, Lidstrom was named a scout for the Red Wings.  On 28 February 2014, Lidstrom was inducted into the Michigan Sports Hall of Fame.  During the 2013-14 season, Lidstrom had his number 5 jersey retired by the Red Wings. Initially, ceremonies were planned for the previous season, on 5 February 2013 -- however, the lockout had made it hard to determine when Lidstrom would able to attend the ceremony. The Red Wings officially retired his number on 6 March 2014, in a pre-game ceremony at Joe Louis Arena.
