WATCH: NBA fan permanently banned after this allegedly 'racial' altercation with a star player

A Utah Jazz fan was banned permanently from attending games at the team's arena Tuesday after a profane and allegedly racist altercation with an opposing team's player, ESPN reported.

The altercation was between Jazz fan Shane Keisel and Oklahoma City Thunder point guard Russell Westbrook. Each individual has a different story about what actually happened, and Westbrook was fined $25,000 by the NBA for making threatening comments to the fan and his wife.

Here is a video of Westbrook talking to the fan during the game, telling him "I'll f*** you up. You and your wife, I'll f*** you up."

Westbrook claims Keisel and his wife told him to "get down on my knees like you used to" according to a statement.

"To me, that's just completely disrespectful, to me, I think it's racial, and I think it's inappropriate in the sense that there's no protection for the players," Westbrook said in his statement.

Keisel was interviewed by KSL-TV after the game, and told a different story, claiming he said nothing vulgar to Westbrook at all, but rather that he was telling Westbrook to "Ice those knees up."

The Jazz, apparently, believed that Keisel was in the wrong, issuing a permanent ban.

"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," Jazz president Steve Starks said in a statement.

What possibly hurt Keisel's case is a series of vulgar and racist tweets that other users dug up in the wake of the confrontation with Westbrook. Some of the tweets were from last season and insulted Westbrook. Others included racial slurs.

"Westbrook is a piece of classless s***," Keisel allegedly wrote in a tweet on the now-deleted page. "Somebody needs to kick his ass."

Keisel has denied authoring the tweets.
