The San Antonio Spurs beat the Oklahoma City Thunder while their fans beat each other.

TNT caught a piece of the fight during a break in the play.

If you take stock in YouTube comments, the fight started when an inebriated Oklahoma City fan waved a Kevin Durant jersey in the air. An equally inebriated San Antonio fan snatched the jersey away. This angered the Thunder fan who punched the Spurs fan and then chaos erupted.
