Niedermayer, who became the third player in Ducks history to have his number retired - after Selanne and Kariya - said, "It's an amazing honor my number will be up there with you two guys."
Inducted into the Hockey Hall of Fame in 2013, Niedermayer was the first player in hockey history to win a Stanley Cup, Olympic gold medal, World Championship, World Cup, Memorial Cup and World Junior title. He is also the only player in hockey history to have won a combination of four Stanley Cups and two Olympic gold medals. A 2003-04 James Norris Memorial Trophy winner as the NHL's top defenseman, Niedermayer was named an NHL All-Star six times during his NHL career (1998, 2001, 2004, 2007, 2008 and 2009).
Of the numerous Ducks records he has held, one was actually eclipsed tonight, as Cam Fowler's assist on Anaheim's fourth goal of the game gave him 205th in his Ducks career, passing Niedermayer for most all time among franchise defensemen.
"His legacy here will be something nobody will be able to fill," Fowler said. "For me, it's a great accomplishment. I hope everything for him was fantastic because he's well-respected and well-loved around here. He deserves the best. I hope he had a great night."
The Ducks all wore jerseys with the number 27 and Niedermayer on the backs during warmups.
"It was a pretty special night," Fowler said. "As players here, we have to pay tribute to the guys who came before us and some of the legends who helped grow the game around this area. Nobody bigger than Scotty. To wear his jersey during warmups, listen to him speak, listen to guys speak before the game was really special. I don't know if it gave our guys a jolt, but it was one of our best games in a long time."
The Ducks actually trailed early when Alex Ovechkin's 40th goal of the season put the Caps on top 1-0 five minutes in, a shot from the left wing on the power play that snuck under Millers armpit.
Henrique got his first of two on that night early in the second, getting his stick on a Brandon Montour one-timer from the point and bouncing it under goalie Braden Holtby.
