Free agent Rasheed Wallace left Detroit Pistons to sign with Boston Celtics on Wednesday.

Terms of the reported two-year deal were not released. Wallace earned 13.68 million U. S. dollars last season, his last of a five-year contract with the Detroit Pistons.

The four-time All-Star forward joined Boston's Big Three of Ray Allen, Kevin Garnett and Paul Pierce as the Celtics hopes to recapture the NBA championship.

Wallace averaged 12 points for the Pistons last year, the 14th straight season in which he's scored at least 10 per game.

Wallace has averaged 15 points and 6.9 rebounds with 1.4 blocks while playing almost 34 minutes per game in his 14 seasons. He started 943 of his 1,009 regular-season games.

When the season starts, Wallace will be 35, Allen 34, Garnett 33 and Pierce 32.

Allen has one year left on his deal, Pierce has two and Garnett has three.
