Boston Celtics All-Star Jaylen Brown will miss "a week or two" after suffering an adductor strain during Wednesday's win against the New Orleans Pelicans.
Brown, who scored 41 points in that win, told reporters after the game that he had tweaked his groin, but he was not officially ruled out of Thursday's road game against the Brooklyn Nets until 90 minutes before the contest.
The 26-year-old is enjoying a career-best season, setting new personal bests in points per game (27.2), rebounds (7.1), field goal percentage (49.8) and free throw percentage (79.5) – all while playing in 40 of the Celtics' first 42 games.
Boston head coach Joe Mazzulla said Brown had tried to warm-up in preparation for the Nets, but was unable.
"I anticipate [his absence] being pretty short – probably a week or two," he told reporters. "I'm not sure what the timeline is.
"I know he tried to give it a go today, and wasn't able to do it. We'll know more in the next couple days, see how he responds."
Celtics center Robert Williams III has a chance to eclipse 25 minutes for the first time this season in the absence of both Brown and starting big Al Horford (lower back stiffness), while the Nets will also be without Kevin Durant as he recovers from a knee injury.
The Celtics entered Thursday's game with the best record in the NBA at 30-12, while the Nets are two games back at 27-13.
