Pietrus headed to Celtics

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.

Boston now has a capable backup to Ray Allen at shooting guard and Paul Pierce at small forward. He was almost traded to the Toronto Raptors two weeks ago but the Raptors were concerned about a July knee surgery that had not completely healed.

According to an NBA source, the knee is not seriously damaged and Pietrus is expected to be 100 percent in about two weeks. It is uncertain if he is capable of playing right now. He did not play in either of Phoenix's two preseason games.
