Nothing official has been said either way, but the news and the team's prior history don't bode well for Terrence Williams.
Williams up on charges | Boston Herald
Celtics president of basketball operations Danny Ainge declined comment yesterday. The Celtics, as always in these situations, are also investigating what took place. Ainge did say that he hadn’t talked to Williams since being informed of the arrest. The incident casts an uncertain light on Williams’ future with the C’s. He has a $947,907 contract for next season that will be guaranteed only if he makes the team in training camp.

Williams has one more year left on his contract, but it's not guaranteed. If these allegations are found to be true, don't be surprised if this incident hurts, and maybe ends, his chances of remaining with the team. When Sebastian Telfair was arrested on a gun possession charge during his time with Boston, the team removed Telfair's nameplate from his locker. Managing partner Wyc Grousbeck wrote an email to the Boston Globe at the time, writing in part: "The facts and circumstances of his case have not been determined but (Telfair) does not have a Celtics locker and we do not anticipate that he will."
Satisfaction guaranteed? - Boston Celtics Blog - ESPN Boston
Williams is set to earn $947,907 next season. If not waived on or before June 30, $200,000 of his contract becomes guaranteed. If not waived on or before Sept. 1, $300,000 becomes guaranteed. And Williams' contract becomes fully guaranteed if he's not waived on or before Oct. 31 (meaning he'd have to make the opening-day roster).
