Brooklyn Nets All-Star Kyrie Irving has been fined $25,000 by the NBA for directing obscene language toward a fan.

The NBA announced the fine on Thursday with the incident occurring in the second quarter of Monday's 114-107 loss to the Cleveland Cavaliers.

Irving responded with obscene language to a fan who could be heard heckling the 29-year-old former Cavaliers point guard. He said: “Got y’all a championship and m***********s still ungrateful.”

Nets teammate Kevin Durant along with New York Knicks' Julius Randle have also been fined for obscene language this season as the NBA attempts to crack down on the use of profanity.

Irving was making his fifth appearance in the NBA this season, due to his vaccination status which meant he could not play home games in New York City, with the Nets not wanting him on a part-time basis. The Nets reversed that decision last month, allowing him to play in road games.

Irving has averaged 22.0 points, 5.0 rebounds and 5.4 assists since his return this season.
