Early in the fourth quarter of Wednesday night’s first round playoff game against the Philadelphia 76ers, Washington Wizards guard Russell Westbrook left the court with a right ankle injury. As Westbrook departed, television cameras showed a fan at Philadelphia’s Wells Fargo Center dumping popcorn on Westbrook, who was irate and had to be restrained by security personnel.

After his team’s 120-95 loss, which put the Wizards in a two games to none hole, Westbrook said the incident was the latest issue he’s had with fans taunting him in a disrespectful manner. For instance, when Westbrook was a member of the Oklahoma City Thunder and playing in Philadelphia in October 2016, a 76ers fan sitting underneath the basket who happened to be a urologist flipped off Westbrook and was ejected. But the problem isn’t just in Philadelphia. It’s league-wide, according to Westbrook.

“I’m all for the fans enjoying the game,” said Westbrook, who isn’t sure of the severity of his injury or if he’ll be available for Saturday’s Game 3. “It’s part of sports. But there are certain things that cross the line.”

He added: “They wouldn’t do that (expletive) anywhere else in any other setting. I’m sick and tired of it, honestly.”

Westbrook said he hopes the NBA would have guidelines with regards to fan behavior and protecting players.

“The rules should be put into place where fans come to the game and know the consequences of what could happen if they are doing certain things or saying certain things that to me are disrespectful like tonight,” he said. “Hopefully the league does whatever it is they’re supposed to do. But I’ve been in many instances where they’re not always taken care of.”

Valerie Camillo, president of business operations for the Wells Fargo Center, released a statement late Wednesday night saying, “This was classless, unacceptable behavior, and we’re not going to tolerate it at Wells Fargo Center.”

Still, Westbrook noted that he’s spoken numerous times about the league doing a better job of putting players in a safe position.

“The protection of the players is very important,” he said. “I’ve been emphasizing this since I’ve been in the league. For me, I get a different reaction from a crowd for whatever kind of reason. I really take this very, very personal. I’m tired of this. It’s the same thing. To me, I really don’t see nothing changing. It just gets worse.”

Westbrook’s teammates came to his defense. Forward Davis Bertans, who was held scoreless and fouled out, said that the incident was “stupid” and added, “I think it’s unacceptable. There’s no place for fans like that that in this game.”

Guard Bradley Beal, meanwhile, echoed those sentiments.

“It’s disgusting,” said Beal, who scored a game-high 33 points on 14-of-28 shooting from the floor. “Us as players, we don’t get to protect ourselves. We can’t run into the stands and confront somebody who’s disrespecting us. We’re here to entertain everyone in this arena. Granted, there may be one bad apple or whatever the case may be, but that’s still not a good look for the city and for the team and for all fans.”

He added: “At the end of the day, we’re going to have to protect the players. There’s a million cameras in here. There’s no way we can’t find out who did it. They should never be able to step foot into an arena nowhere in the U.S.”
