Williams missed Monday night's 101-98 loss to the Miami Heat with the same injury.
Williams suffered the injury after a collision with Boston Celtics center Greg Stiemsma Saturday night. Williams, who felt a foul should have been called on Stiemsma on the play, received a technical foul for arguing the call.
The 27-year-old All-Star is averaging 21 points and 8.7 assists in 55 games for the Nets (22-40), who have just four games remaining in what is their final season in New Jersey.
Small forward Gerald Wallace (strained right hamstring), who has missed the past four games, is questionable.
