The Boston Celtics have reached an agreement with Rasheed Wallace, according to a source.

Wallace is expected to get a two-year deal using the mid-level exception (expected to be about $5.6 million to $5.8 million).

Kevin Garnett, Ray Allen, and Paul Pierce, owner Wyc Grousbeck, coach Doc Rivers, and president Danny Ainge met with Wallace last week. Wallace turned down overtures from Orlando and San Antonio to commit to Boston.
