Růžička also had a short career in the NHL, being selected by the Toronto Maple Leafs 73rd overall 1982 NHL Entry Draft. He played five seasons for the Edmonton Oilers, Boston Bruins and Ottawa Senators. His best season statistically came in 1991–92 when he recorded 75 points (39 goals, 36 assists) with Boston. He has a Stanley Cup ring and is on the 1990 Edmonton Oilers Stanley Cup team picture. However, Růžička only played 25 regular season games and did not appear in the playoffs that season. Thus, his name was not engraved on the Stanley Cup.
