The 43-year-old veteran announced his decision moments after Boston beat Vancouver 4-0 in Game 7 of the Stanley Cup finals. Recchi had one assist in the game.
"I'm done. Yeah that's it," Recchi said. "I couldn't ask for a better way to go out and to do it with this team was even more special. I love these guys. This is what we set out to do and we did it."
ESPNBoston.com confirmed prior to Game 7 that Recchi would retire after the game regardless of the outcome.
"We've talked about it and I had a glass of wine with him yesterday and it's probably the last glass with him before a game ever," veteran winger Shawn Thornton acknowledged earlier Wednesday. "So everyone loves 'Rex' and appreciates everything he's done for us. I'm a big supporter of his and I'm hoping we can do it for him."
In terms of lifetime achievements, Recchi joined a rather exclusive list. He is just the eighth player in NHL history to win a Stanley Cup in three different decades -- he won in 1991 with the Penguins and 2006 with the Carolina Hurricanes -- and the third player to win a Stanley Cup with three different teams, joining Joe Nieuwendyk and Claude Lemieux.
Recchi can take satisfaction in being the lone member of one list. He was the only player on the current Bruins roster who was alive the last time the Bruins won the Stanley Cup.
