Watch: Russell Westbrook reacts to 76ers fan flipping him off

An angry Sixers fan flipped Russell Westbrook the double bird during the Thunder-76ers season opener on Wednesday night in Philly - and ESPN caught it all on camera.

It happened on a pretty ordinary play. Westbrook got the acrobatic and-one, faced the crowd, and the fan just went nuts.

Westbrook reacted beautifully. He gestured to the fan as if to say, " Can he really do that?"

Video warning: The fan yells NSFW language at Westbrook.

That's perfect. Westbrook stays calm and cool. He walked into this game with a kilt on. This isn't fazing him. He's not going to lose his temper over something as small as this.

ESPN's Royce Young reported that the fan was escorted out of the arena.

Fans, please refrain from yelling profanities and flip off the players. There are children at the game, and it's just not cool.
