Fresh off of their first loss of the season, the Boston Celtics faced off against a pair of old friends on Friday night, looking to return to their winning ways. Visiting Charlotte to face off against former lead assistant coach Charles Lee, former Celtics forward Grant Williams and the Hornets, the Celtics found themselves facing a sturdier test than they might have anticipated. After 40 minutes of back-and-forth basketball, though, the Celtics managed to distance themselves in a fourth quarter that featured significant frustration — and multiple ejections — from the Hornets. The Celtics advanced to 5-1 with a 124-109 win.
