Rudy Gobert freaked out during the Timberwolves' win over the Hawks on Monday night ... when an apparent horn fell from the arena's scoreboard -- and landed right in front of the NBA star.
The malfunction was caught on the TV broadcast at the end of the first quarter of the showdown at the Target Center in Minneapolis.
The Wolves center was heading toward his team's bench after the buzzer ... when the black piece of equipment came crashing to the court, nearly hitting Gobert.
