To Russell Westbrook’s defense, here is even further proof of his previous interactions with Utah Jazz fans. In this video, @russwest44 is called a “boy” by a Jazz fan ahead of Game 4 of OKC’s first-round playoff series against Utah on April 23, 2018 at Vivint Arena. pic.twitter.com/lc6slA7fTo

UPDATED 5:22 p.m. ET: The Utah Jazz have issued a lifetime ban on the fan who kicked off an altercation with Russell Westbrook on Monday night. 

"Everyone deserves the opportunity to enjoy and play the game in a safe, positive and inclusive environment," said Utah Jazz president Steve Starks in a statement announcing the ban. "We all have a responsibility to respect the game of basketball and, more importantly, each other as human beings."

After news of the ban broke, the NBA announced that  Westbrook will be fined $25K for "directing profanity and threatening language to a fan."

See original story below.

During Monday night's game against Utah, Oklahoma City's Russell Westbrook went off on a Jazz fan.

"I'll f*ck him up. I promise you [...] I'll f*ck you up. You and your wife. I'll f*ck you up [...] On everything I love," Westbrook can be heard saying.

After the game, Westbrook talked about what went down. 

Westbrook: "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"

It's not the first time Westbrook has had problems with Jazz fans. 

"I don't confront fans, fans confront me," Westbrook said back in 2018, per USA Today. "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.
