Just one week Sebastian Telfair was arrested on a gun possession charge, the Boston Celtics are severing ties with the guard after one season.

"I wanted to let you know that we have removed Sebastian's nameplate from his locker in Waltham. The facts and circumstances of his case have not been determined but he does not have a Celtics locker and we do not anticipate that he will," Celtics managing partner Wyc Grousbeck wrote in an e-mail to the Boston Globe on Tuesday.

Telfair's playing time became increasingly limited as Boston's disappointing 2006-2007 season went along.

Telfair's cousin, New York Knicks point guard Stephon Marbury, showed up to support him hours before he was arraigned, the Daily News reported on its Web site.

"The players on the Celtics have been explicitly warned, this year, to obey the team and league gun prohibition as well as state laws. We take this very seriously and will act accordingly once the facts have been determined," Grousbeck said Friday night.
