Jean Guy Morissette's only NHL game was as an injury replacement for Montreal goaltender Gump Worsley.
In the game, however, Morissette gave up 4 goals in 36 minutes before he, too, was seriously injured. His cheekbone was broken, and he would miss a significant part of the season as Charlie Hodge was called up.
Hodge of course went on to record a spectacular season behind a strong Habs team. Hodge in fact won the Vezina trophy that year and would go onto play in a total of 358 NHL games.
Morissette, on the other hand was returned to the minor leagues upon his injury being fully heeled, never to return to the NHL ever again.
Too bad for Jean-Guy, as he could have had a really good shot at full time NHL employment for at least the 1963-64 season.
