San Antonio Spurs player Patrick “Patty” Mills was subjected to racist slurs Sunday at the Quicken Loans Arena in Cleveland, according to a video circulating on social media.

Microphones captured a man taunting Mills as he attempted to shoot a free throw during an NBA game against the Cleveland Cavaliers on Sunday.

A Twitter user asked whether she was the only one who heard the insults.

“Hey Jamaican dog, they want their bobsledder back,” a man can be heard yelling at Mills.

Mills, who isn’t Jamaican, but a native Australian from the Torres Strait, responded on Twitter at the taunts directed at him.

The Spurs defeated the Cavaliers 110-94.
