SALT LAKE CITY (AP)-A Utah Jazz fan is suing for $100 million after being banned for life from Vivint Smart Home Arena over what were called racial taunts directed at then-Oklahoma City point guard Russell Westbrook.

The lawsuit says Shane Keisel denies making racial remarks while heckling Westbrook during a game in March.

He says the high-profile incident has cost him his job and exposed him to violent online threats. The Jazz stand by their decision to ban him. Team officials say they investigated what happened and will fight the lawsuit.
