Mickael Pietrus, recently released by the Phoenix Suns, is leaning "heavily" towards signing with the Boston Celtics, according to a league source.



Pietrus must first clear waivers -- that won't happen until 6 p.m. Saturday -- but it's highly unlikely that any team will want to pick up the $5.3 million he is owed this season.



The 6-foot-6 wing forward has been a player that Danny Ainge, Boston's president of basketball operations, has expressed interest in acquiring in the past.
