Williams has been out since March 27 with a torn meniscus. A “final determination (on when he returns) will be made on how Williams feels day-to-day,” Charania reported.
The Celtics hold a 2-0 series lead, with Game 3 slated for Saturday at Brooklyn. Game 4 will be held Monday, also in Brooklyn.
Williams, 24, is in his fourth NBA season. He appeared in 61 games this year, all starts, compiling career-high averages of 10.0 points, 9.6 rebounds and 2.2 blocked shots.
