BOSTON -- The Boston Celtics announced today that they have waived forward/center Rasheed Wallace after coming to a mutual agreement following which Wallace plans to retire.

"We would like to thank Rasheed for everything that he did for this team and organization last season," said Danny Ainge, Celtics President of Basketball Operations. "We would like to wish Rasheed and his family the best as they move on into the next phase of their lives. He will always be a member of the Celtics family."

Wallace, a 6-foot-11 center/forward, averaged 9.0 points and 4.1 rebounds in 22.5 minutes per game last season for the Celtics. He averaged 6.1 points, 3.0 rebounds and shot 34.5 percent from 3-point land during the Celtics' run to the 2010 NBA Finals. The 15-year pro was originally signed by the Celtics as a free agent on July 8, 2009.
