Tristan Thompson is in trouble with the NBA.
The Cleveland Cavaliers player was fined $15,000 for “making an inappropriate gesture toward a spectator,” the league announced Thursday.
The incident occurred at the end of the Dec. 3 game against the Brooklyn Nets at the Barclays Center.
In video footage obtained by TMZ, Thompson is seen seemingly giving the middle finger to members of the crowd after the Brooklyn Nets missed a final three-point shot in an attempt to secure a buzzer-beating win.
While the Cavaliers won 99-97 victory, Thompson was rewarded with the fine.
The 23-year-old model and Keeping Up with the Kardashians star was sitting courtside at the Wells Fargo Center in Philadelphia, watching the Cavaliers play the Philadelphia 76ers (Simmons’ team), when the two athletes were separated from each other in the fourth quarter of the game.
According to Cavaliers Nation, the tension between Simmons and Thompson boiled over when Thompson made a free throw and “proceeded to taunt” Simmons. In response, Simmons seemingly gave the middle finger to Thompson.
Showing her support for Simmons, Jenner jokingly booed and laughed during the free throw, as seen in a video shared by Instagram account House of Highlights.
There were no hard feelings on Thompson’s part. After the game, he retweeted a clip of the moment — writing, “Ben Simmons is my bro.”
The Cavaliers beat the 76ers, 121-112.
