Here is the exchange:

After the game, Westbrook explained what caused him to react like that. The NBA star said the Jazz fans told himto get down on your knees like youre used to. Westbrook felt like the comments were racial, which is why he was so enraged:

The Utah Jazz fan wasShane Keisel. In an interview withKSL5TV, says that he told Westbrook to ice his knees. Not get down on his knees.

Miami Heat star Dwyane Wade wasn't buying it:

Also, retired NBA player Matt Barnes commented on the exchange, saying Utah fans have the "most racist fans in the NBA:"

Of course, NBA Twitter started pulling up old tweets from Keisel, who seems to be a Donald Trump supporter and not a fan of Westbrook.

This isn't the first time Westbrook had an intense exchange with Jazz fans. Last years officials had to hold him back from going after a fan.
