"I’m very excited to expand my role with the Ducks and take on a new challenge," the 39-year-old Niedermayer said in a statement. "I’m grateful to [general manager] Bob Murray, Bruce Boudreau and the Ducks organization for giving me this opportunity and can’t wait to get started."
Niedermayer scored 172 goals and 568 assists for 740 points in 1,263 games over 18 seasons in the NHL, the last five with Anaheim.
Few players in pro hockey history enjoyed his level of team success. Niedermayer won three Stanley Cups with New Jersey and one with the Ducks to go along with an Olympic gold medal, world championship and World Cup title.
"As a player, Scott was one of the great leaders and winners of all time, making him a tremendous addition to our coaching staff," Murray said in a statement. "His knowledge of the game and relationship with the players will be a great benefit for us. And he's even a better person than a hockey player."
Since retiring in 2010, Niedermayer has served as a spokesperson for the World Wildlife Fund, opposing the Enbridge Northern Gateway pipeline in his native British Columbia.
The Cranbrook, B.C, native was inducted into the Canadian Sports Hall of Fame last year and also had his jersey number retired by the Devils.
