The Jets signed goaltender Markus Mattsson during the summer of 1977 and he spent most of the 1977-1978 season as the third-string goaltender behind regulars Joe Daley and Gary Bromley. The Jets traded him to the Quebec Nordiques in February 1978, but after a brief and disastrous tenure in Quebec, the Jets later re-acquired him on account of an injury to Daley. After a difficult rookie season, Mattsson carried the bulk of the load for the Jets in 1978-1979 and showed much promise, though he did not see any action in the playoffs as the Jets captured the AVCO Cup championship. The Jets protected his rights going into the NHL, but he did not develop as they had hoped and he split the next two seasons between the Jets and their farm team in Tulsa. After spending the entire 1981-1982 season in Tulsa, he moved on and spent time with the Minnesota North Stars and Los Angeles Kings before returning to his native Finland to wind up his playing career.
