Russell Westbrook has been fined $25,000 by the NBA "for directing profanity and threatening language to a fan."

The fan in question has been permanently banned by the Utah Jazz.

"Everyone deserves the opportunity to enjoy and play the game in a safe, positive and inclusive environment," Jazz president Steve Starks said in a statement Tuesday. "Offensive and abusive behavior does not reflect the values of the Miller family, our organization and the community. We all have a responsibility to respect the game of basketball and, more importantly, each other as human beings. This has always been a hallmark of our incredible fan base and should forever be our standard moving forward."

Video of Westbrook saying, "I'll f--- you up" to Jazz fan Shane Keisel and his female companion.

Westbrook said Keisel told him to, "Get on your knees like you're used to," a comment Westbrook considered "completely disrespectful" and "racial."

Keisel was one of several fans who received a warning card for violating the NBA's fan code of conduct, denied saying anything inappropriate, claiming that he told Westbrook to "Ice those knees up!" According to Keisel, after Westbrook replied that it was heat on his knees, Keisel hollered, "You're going to need it." Keisel said his girlfriend, Jennifer Huff, didn't participate in the exchange.

Raymond Felton and Patrick Patterson confirmed Westbrook's side of the story. The Jazz also gathered intelligence that verified Westbrook's version.
