Draymond Green revealed a fan said "threatening stuff to my life" leading to him asking officials to have him thrown out of the Fiserv Forum during Tuesday's 128-111 Milwaukee Bucks win over the Golden State Warriors.

The Warriors power forward was involved in a heated exchange with a fan who had heckled him courtside while Giannis Antetokounmpo shot free-throws with 6:30 remaining in the third quarter of the game with the Bucks up 81-59.

The situation threatened to boil over, but Green walked away before asking the referees to get security staff to eject the fan amid boos from the home crowd.

"Some threatening stuff to my life," Green told reporters when asked what was said to set him off from the exchange, having been fined $25,000 last week after a verbal altercation with a Dallas Mavericks fan.

"I was this close to really going back and diving on him. I just went back and told the official. When I told the official, he said, 'he's gotta get out of here'. You gotta get out of here."

Green added that he feels there needs to be consequences for fans who step over the line with such comments.

"There are no real consequences," Green said. "Yeah, you can't come back to the game, or even if you get arrested, nothing really happens.

"You just hope it gets to a point where these leagues can work with legislators to implement laws, because that's the only thing that's really going to correct the issue."

Home team Milwaukee said in a statement that the fan's ejection was "under the referee's digression" and that they would investigate the situation alongside the NBA.
