Oklahoma City Thunder star Russell Westbrook took exception to something said to him by a Utah Jazz fan during Monday's game.

The Deseret News' Eric Woodyard shared a video in which Westbrook can be heard saying, "I'll f--k you up. You and your wife. I'll f--k you up." (warning: post contains profanity):

Westbrook commented on the altercation after the game, via Andy Larsen of the Salt Lake Tribune: "The realization of it is, how it started was, a young man and his wife in the stands told me 'to get down on my knees like you used to.' To me, that's just completely disrespectful, to me, I think it's racial, and I think it's inappropriate."

Thunder forward Patrick Patterson supported his teammate on Twitter (warning: post contains profanity):

The fan, Shane Keisel, shared his side of the story, via Jeremiah Jensen of KSL TV:

The Jazz released a statement regarding the incident, via Tim MacMahon of ESPN.com:

"We are continuing to investigate the unfortunate exchange at tonight's game between Russell Westbrook and fans. Multiple warning cards were issued by arena security. Players and fans have a shared responsibility to create a safe and respectful environment. If it is determined that any fans violated the NBA Code of Conduct, appropriate action will be taken."

According to Woodyard, five fans at Vivint Smart Home Arena received a formal warning that their "comments, gestures and/or behaviors directed at players were in violation of the NBA Fan Code of Conduct." The fans subsequently returned to their seats.

Westbrook has had issues with Jazz fans before.

As he was walking off the court following Oklahoma City's Game 6 loss to Utah in the first round of the playoffs last April, he swiped in the direction of a fan.

"I don't confront fans, fans confront me," he told reporters. "Here in Utah, man, a lot of disrespectful, vulgar things are said to the players here with these fans. It's truly disrespectful. (They) talk about your families, your kids. It's just a disrespect to the game and I think it's something that needs to be brought up."
