The Ducks announced the honors for their Hall of Famers on Monday.
Kariya’s No. 9 will go into the Honda Center rafters on Oct. 21, and Niedermayer’s No. 27 will be raised Feb. 17.
Teemu Selanne‘s No. 8 is the only number previously retired by Anaheim.
Kariya spent his first nine NHL seasons with the Ducks, spending seven seasons as Anaheim’s captain and teaming with Selanne as a potent, speedy scoring duo. He is the fourth-leading scorer in Ducks history with 669 points.
Niedermayer spent his final five NHL seasons with the Ducks. He was their captain when they won the franchise’s only Stanley Cup title in 2007.
