Report: Jaylen Brown Enters Concussion Protocol, Out Indefinitely

Boston Celtics guard Jaylen Brown, who escaped serious injury when he hit the back of his head and neck late in the third floor of Thursday’s game in Minnesota, has entered the NBA’s concussion protocol.

Brown will be out indefinitely, the Celtics said Friday.

Brown crashed hard to the floor after slipping off the rim on a two-handed dunk. He walked off the court on his own and later left the arena to undergo a CT scan. He rejoined the Celtics for their trip to the airport and traveled with the team back to Boston.
