At the age of 24, Morrison finally got the chance to play in the NHL when the Detroit Red Wings called him up for 40 games in 1947-48. The team was stacked with offensive talent, led by the likes of Howe, Ted Lindsay and Sid Abel. Morrison was asked to concentrate primarily on his defensive duties but still managed to contribute ten goals and 25 points. The Red Wings advanced to the Stanley Cup finals that year, losing in four straight games to the Toronto Maple Leafs. Morrison was back for another 13 games in Detroit the following year but was used much more sparingly. The club again advanced to the Cup finals, only to suffer the exact same fate as the previous year, losing in four straight to the powerful Maple Leafs.
In the summer of 1950 Morrison was part of a huge NHL trade which also saw Harry Lumley, Jack Stewart, Al Dewsbury and Pete Babando head to the Chicago Blackhawks in exchange for Jim Henry, Bob Goldham, Gaye Stewart and Metro Prystai. Morrison played in 59 games with Chicago in 1950-51, scoring eight goals and 20 points.
Despite turning in a decent season for the Blackhawks, Morrison was relegated to the St. Louis Flyers of the AHL the following year where he scored 60 points in 65 games. Rather than continue any longer in the minors, he retired at the end of the 1951-52 campaign at the age of 28. Morrison and his brother Rod were teammates with the Red Wings in 1947-48, when Rod suited up for 34 games.
