After leaving the Celtics' win Thursday night against the Miami Heat in the third quarter, Jaylen Brown has been ruled out of Boston's next game against the Dallas Mavericks on Saturday.
Josh Richardson status remains unknown.
While leading the Celtics in scoring during their best game of the season, Brown left the third quarter and was ruled out with hamstring tightness. Head coach Ime Udoka after the game expressed the team's desire to be conservative with the star wing, but Friday's injury report served as the only update since.
Richardson, meanwhile, was expected to get X-rays on a foot contusion. He was out against Miami, but his upgrade to questionable as Boston travels to Dallas is encouraging.
