Celtics center Robert Williams III will be out for at least two months after surgery Friday on his right knee, which prevented him from playing full time for Boston in the NBA Finals last season.
The team reported that the arthroscopic surgery to remove small pieces of cartilage from Williams III and address the swelling was successful. The player is expected to resume basketball activities within 8 to 12 weeks.
Williams III underwent surgery in March to repair a cartilage tear in the same knee. He did not see action for seven postseason games due to his rehabilitation from that surgery and because he later had sore knee and bruised bone.
The pivot, solid defensively and playing his fifth season in the NBA, had an average of 10 points last season, the highest figure in his career, and 9.6 rebounds. But those numbers dropped to 7.6 points and 6.2 rebounds during the playoffs.
Danilo Gallinari also underwent surgery on Friday. The Italian forward, who signed as a free agent in July, tore the anterior cruciate ligament in his right knee while he was playing for Italy in a match against Georgia in FIBA World Cup qualifying.
Gallinari tore the same ligament in 2013. The Celtics did not specify a date for his return. However, those types of injuries ordinarily involve a recovery process of up to a year, which would mean the experienced player could potentially miss the entire season.
