Paul Pierce has just signed with the Boston Celtics, which will allow him to officially retire as a member of the team that he spent his first 15 NBA seasons with.

In announcing Pierce's signing today, Celtics co-owner Wyc Grousbeck also reiterated the organization's plan to retire the #34.

Per ESPN,

"We're honored that Paul has chosen to retire as a Celtic. He is among the very best Celtics -- a champion on and off the court," Grousbeck said in a release. "We congratulate Paul on a Hall of Fame career, and look forward to seeing his number raised to the rafters of TD Garden."

Pierce added,

"It's an honor to have this opportunity to once again call myself a Boston Celtic," Pierce said in the release. "The organization and city took me in and made me one of their own, and I couldn't imagine ending my career any other way. I'm a Celtic for life."

Pierce, who was named to 10 All-Star teams and won a championship with Boston in 2008, ranks second all-time in the Celtics organization in points scored (24,021) trailing only John Havlicek.
