With Kevin Garnett heading to Boston, his days of wearing number 21 are over.

The Celtics retired 21 back in 1966 to honor Hall of Famer Bill Sharman.

Jeff Twiss of the Celtics has informed RealGM that it appears  Garnett will wear number 5.

Paul Pierce and Ray Allen will be attending Tuesday's press conference, along with Garnett, Danny Ainge and Doc Rivers.
