BOSTON — Rob Williams is going to be out much longer than initially expected.
The Celtics announced Friday that Williams had successful left knee surgery to remove loose bodies and address swelling, and the center is expected to return to basketball activities in 8-12 weeks. Earlier this week, it was reported that Williams was expected to return in 4-6 weeks and only miss the early portion of the regular season, which begins on Oct. 18.
Williams’ procedure was performed by Celtics team physician Dr. Tony Schena at New England Baptist Hospital.
