Seventy-one years later, the organization will retire that same number in his honor prior to the game against the Toronto Maple Leafs at Little Caesars Arena on Friday (7:30 p.m. ET; FS-D, TSN4, NHL.TV).
"Amazing, isn't it?" Kelly, 91, said Wednesday. "I fought against having it, but it seemed to work out well in the end. Very well."

The Red Wings are the second team to ensure no one ever wears Kelly's No. 4. The Maple Leafs retired that number on Oct. 13, 2016 in tribute to both Kelly and forward Hap Day.
"It's nice that they are doing this on a night both those teams are playing against each other," Kelly said. "All for a number I was reluctant to get."
Kelly came to Red Wings training camp as a 20-year-old with no expectations in 1947 and was surprised when he was kept on as the team's fifth defenseman. He was given No. 20, a number he said he was comfortable with.
Various injuries to his teammates allowed Kelly to move into the top four midway through the season. He responded by getting 20 points (six goals, 14 assists) in 60 games while showcasing his skill as a shutdown defenseman.
With his role having increased during the course of his rookie season, management figured his number should change, too, when he showed up for training camp in 1948.
"I came back and they gave me No. 4," Kelly said. "I kind of complained about it. I said: "I like 20." They said: "No, that's two numbers … we want you to have No. 4, so they gave me No. 4. And that's the number I had for the next 19 years.
"It was a great run. I spent 12-1/2 seasons with Detroit, 7-1/2 with Toronto. We won seven consecutive League championships and four Stanley Cups (1950, 1952, 1954, 1955) in Detroit, then four Stanley Cups in Toronto (1962, 1963, 1964, 1967)."
