The Celtics have had enough scary moments this season, but they suffered another fright against the Timberwolves Thursday.
Jaylen Brown is known for crazy athleticism and serious dunking ability, but one throw down backfired against Minnesota.

Brown got loose on a fast break, side-stepped a defender and threw it down through a foul, but after touching the rim he got off balance and fell down hard on the back of his head.

Holy hell. Jaylen Brown with the HARD fall after the slam. We really, really hope he's okay.

The 21-year-old was down for a good amount of time and the Celtics training staff brought a stretcher out as a precaution. Fortunately, Brown eventually got up and walked off the court on his own power. He looked understandably dazed walking off the court.

The Celtics announced he was suffering from concussion-like symptoms and would be out for the game.
