Woj: Robert Williams out 4-6 weeks following knee surgery

Boston Celtics center Robert Williams is expected to miss 4-6 weeks following knee surgery for a torn meniscus, according to ESPN's Adrian Wojnarowski, with him possibly returning to the court in the second-round of the Eastern Conference playoffs.

ANALYSIS: The news could be much worse and the Celtics will likely get Williams back early in the playoffs. He has been an anchor for Boston's outstanding defense this season with the team only one game out of first place in the Eastern Conference with just six games remaining in the regular season.
