Driedger was injured while playing for Canada against Finland in the title game of the world championships. He had surgery on Monday.
Driedger had a rocky first season with the Kraken due to injuries and inconsistency. He played in 27 games and had a 2.96 goals-against average and an .899 save percentage, both the worst marks of his career. Driedger signed a three-year, $10.5 million deal with the Kraken last offseason.
