Swede Knox (born on March 2, 1948 in Edmonton, Alberta) is a former NHL linesman. He had officiated 1,983 NHL games since 1972, and wore a helmet from the mid-1980s until his retirement in the mid-1990s. Knox, as a linesman, later filled in as referee during a game in Toronto in the early 1990s, when Don Koharski couldn't finish the game and Kevin Maguire made his NHL officiating debut as a linesman. The changes were made before the third period. Knox wore Koharski's jersey, while Maguire wore Knox's jersey.
