What is Robert Williams III's injury?
On March 30, the Celtics announced that Williams underwent a partial left knee meniscectomy and was expected to miss four to six weeks.
Williams was sidelined for the remainder of the regular season and missed the opening two games of Boston's first-round matchup with Brooklyn. He returned in Game 3, posting two points and two rebounds in 15 minutes.
After playing five straight games, the Celtics ruled Williams out of Game 4 against the Bucks in the second round with left knee soreness. Celtics head coach Ime Udoka said that Williams had a "little flare-up" that got irritated when he was trying to warm up.
Udoka added that it wasn't unexpected for Williams to have soreness after surgery and that he wasn't expected to undergo further testing.
