Ducks general manager Brian Burke announced Niedermayer's decision at a news conference a half-hour before Wednesday night's game against the Buffalo Sabres.
The defending Stanley Cup champions are hoping Teemu Selanne will soon make the same decision as Niedermayer. Burke and the rest of the team's management said they were not disturbed that Niedermayer and Selanne took the time off. "He deserves that respect," Burke said of Niedermayer. "He's going to be a first-ballot Hall of Famer."
The GM estimated Niedermayer would be ready play his first game in seven to 10 days.
Without Niedermayer and Selanne, the Ducks have been struggling. They got off to a slow start and were third in the Pacific Division with a 12-12-4 record heading into the game against Buffalo.
