Diminutive Jean-Guy Morissette played in just one NHL game but it was a special memory for him, especially getting to play in net for the Montreal Canadiens. The biggest game of his hockey career took place on October 30, 1963 when he got the call to replace Gump Worsley, who was sidelined by an injury in the second period of a game against Toronto. Morissette was Montreal's spare goaltender at the time but had never been pressed into action before He was noticeably nervous in goal, and that was accentuated by the fact he allowed four goals on 17 shots in what resulted in a 6-3 loss to the Leafs.
The lowest point in Morissette's career also came during the 1963-64 season. In fact, it came just one day after his one and only game in the NHL. On October 31, 1963 he was hit in the face with a hard shot which broke his cheekbone. He missed the rest of the season.
Morissette continued to play goal for another eight years, the majority of which were in the AHL and WHL with various clubs. His last two pro seasons were spent with the Grand Falls Cataracts of the Newfoundland Senior League. Both years the team advanced to the Allan Cup championships.
