Miami Heat star Jimmy Butler was fined $15,000 for making an obscene gesture during the team's Game 5 victory over the Atlanta Hawks, the league announced on Thursday.
The organization was also fined $15,000 for sharing the incident on social media, a post that has since been deleted.
Butler made the gesture in the second quarter of the Heat's series-clinching 97-94 victory on Tuesday.
The team's leading scorer missed the contest with knee soreness after averaging 30.5 points per game over the first four contests of the series.
