The Celtics agreed to terms with former Boston College big man Sean Williams, a team source said. He is expected to be in uniform for Friday’s game against the Hawks.
Williams, 25, has bounced around the NBA and international leagues since being a first-round pick of the New Jersey Nets in 2007. He was waived by the Dallas Mavericks March 23. The 6-foot-10-inch center has also played in the NBADL, Israel, China, and Puerto Rico.
Williams has had disciplinary issues since being dismissed from BC, including a 2009 arrest at a Denver mall while with the Nets. The Celtics did considerable background work and believe Williams will be a positive presence in the locker room.
His release from Dallas was because of discipline issues. To make room, the Celtics will waive Jermaine O’Neal, who is out for the season after left wrist surgery.
