The former Senators captain, who spent 17 seasons in the nation's capital and last suited up for Ottawa in 2013, announced his retirement earlier in the day after signing a one-day contract. The 41-year-old then took to the ice for a ceremonial pre-game skate.
In a classy move, current Senators captain Eric Karlsson skated alongside his former teammate in the warm-up and showed his gratitude by allowing Alfredsson to wear the "C" on his jersey.
The franchise's all-time leader in games played (1,178), points (1,108), goals (426) and assists (682) circled the ice to thunderous applause, cheers, and the chanting of his nickname "Alfie."
A teary-eyed Alfredsson was then joined by his family on the ice as he briefly addressed and thanked the fans in Ottawa.
Hinting at a possible return to the Senators down the road in some capacity, the native of Sweden made a point of not saying goodbye to the fans, preferring to say that he would see them soon.
Alfredsson then capped off the festivities with a ceremonial puck-drop.
