This timeline for Brown would have him ready to return to the court in time for training camp.
The Celtics announced Monday that Brown, who averaged a career-high 24.7 points on 48.4% shooting, had a torn scapholunate ligament in his left wrist and would miss the remainder of the season.
Boston is familiar with the procedure as guard Romeo Langford had it Sept. 22. Langford was ready to make his debut in mid-March before he contracted COVID-19 -- about 5½ months after the surgery.
Brown's injury adds to what has been a frustrating season for the Celtics, who are officially headed to the play-in tournament.
