After being drafted by the Hartford Whalers in the 10th round (204th overall) in 1990, Knutsen remained in Europe until 1997, playing for his hometown team Vålerenga, and later Djurgården of the Swedish Elitserien. In 1996, the Mighty Ducks of Anaheim acquired his rights, and he made his debut with the Ducks in 1997. After a disappointing season (playing in part for the American Hockey League (AHL) Cincinnati Mighty Ducks), Knutsen returned to Djurgården. During the 1999–00 season, he was the highest paid player in the Elitserien, earning a salary of $280,000.
