First Disqualification of the Series
A player has just been disqualified from the main event. He was putting chips into his pocket when he was caught by a floorman. The player claimed that he heard it was ok to hide chips in his pocket, but that stuff doesn't fly in the World Series. He has been disqualified, and the floorman went on to say that this was the first DQ of it's kind for the entire WSOP. His chips were confiscated and removed from play. "
