The NFL is investigating an incident involving Dallas cornerback Adam "Pacman" Jones that took place at a downtown hotel on Tuesday night. The incident, called a minor disturbance by the police, occurred in a restroom at the hotel. Jones practiced with the Cowboys on Thursday but was not present in the locker room to address the incident, and Coach Wade Phillips insists that he will play on Sunday against the Cardinals. "I don?t think there is any misunderstanding about the position Adam has put himself in with respect to his behavior," Commissioner Roger Goodell said. "There are certain things I expect of him. I would tell you I?m disappointed we?re even discussing this."
