Woj reports that inside the Celtics Robert Williams could miss the start of the season. He underwent arthroscopy of his left knee and is expected to be out between 4 and 6 weeks.
The training camp starts in a week and the season in 4, which means that he could therefore miss the first weeks of competition.
Recall that in March he had meniscus surgery, but was able to return in time for the playoffs. It is not yet known if this arthroscopy is linked to this meniscus.
