Boston Celtics forward Jaylen Brown will miss tonight's game against the Brooklyn Nets due to a right adductor strain, and he could be sidelined for "a week or two," Celtics coach Joe Mazzulla told ESPN's Tim Bontemps.

"I anticipate it being pretty short," Mazzulla told ESPN prior to the Nets game. "Probably a week or two."

Brown has appeared in 40 games this season, averaging career-highs in points (27.2), rebounds (7.1), field-goal percentage (49.8%) and free-throw percentage (79.5%).

On Wednesday, Brown recorded a season-high 41 points as well as 12 rebounds in a win over the New Orleans Pelicans — Boston's fourth-straight victory. 

The Celtics are currently 30-12, which is the best record in the NBA. Boston's offense has been dominant through the first half of the season, scoring 115.9 points per 100 possessions (which ranks first in the NBA). They also have the ninth-best defense in the league, allowing 109.4 points per 100 possessions.

Brown has been a huge reason for the Celtics' success. In his absence, Boston will be relying heavily on Jayson Tatum, who is also in the midst of a career-year.
