Boston.com has the story: “Just a few minutes after Mickael Pietrus cleared waivers, he agreed to join the Celtics, giving the team’s bench a potential replacement for the injured Jeff Green. Pietrus, 29, was bought out by the Phoenix Suns on Thursday and was a free agent beginning at 6 p.m. today. The Celtics were one of four teams interested in the swingman and he favored the club during the entire process. ‘I have decided to be part of The Boston Celtics Family,’ he wrote on Twitter… Pietrus was the 11th overall pick in the 2003 NBA Draft by the Golden State Warriors and has spent time with the Magic and Suns. Mostly coming off the bench, Pietrus has averaged 8.5 points and 3.1 rebounds. His best year was 2006-07 when he averaged 11.1 points and shot nearly 49 percent for the Warriors.”
