San Jose Sharks goaltender Antero Niittymaki will miss the next 12 weeks after lower body surgery.

The San Jose Mercury News is reporting that Niittymaki had a procedure in southern California to erase pain that he has been having as a result of a lower body injury last season.

The backup to Antti Niemi last season, Niittymaki went 12-7-3 with a 2.72 goals against average in 24 games.

Over seven seasons in the NHL, the 31-year-old Finland native has played in 234 games and is 95-86-31 with five shutouts and a 2.95 GAA with Philadelphia, Tampa Bay and San Jose.

Thomas Greiss will serve as San Jose's backup until Niittymaki can return to play.
