Celtics' Jaylen Brown: Heads to locker room

Brown may have suffered a left hamstring injury as he asked out of Wednesday's preseason game against the Raptors and has headed to the locker room, John Karalis of BostonSportsJournal.com reports.

Brown appeared to grab his left hamstring while asking to be removed from the game. It's uncertain how severe the injury is, but his night might be over, as hamstring injuries are not to be taken lightly.
