The NBA has started handing out Red Cards. Unlike in soccer, where Red Cards are given to players who do something that warrants them getting kicked out of the game these cards are being distributed to fans.
A Reddit user posted a photo of a card they received for their behavior at a game. The card reads that their words, or actions had been abusive to players, officials, or spectators, and it's a one-time warning. If the card holder is found violating the NBA Fan Code of Conduct again then they would be ejected from the game.
Would be great to see a high profile fan, such as Spike Lee, receive one.
