CINCINNATI (AP) - A trial has started for Cincinnati Bengals cornerback Adam "Pacman" Jones, who is charged with assaulting a woman at a nightclub.

Witness testimony began Monday after brief opening statements.

Jones has pleaded not guilty and was released on his own recognizance after his June arrest. He is accused of hitting a 34-year-old woman at a downtown Cincinnati nightclub. A police report listed the injury as apparently minor.

Aside from the legal outcome, Jones could be punished by the National Football League under its conduct policy.

Jones has had previous legal troubles and pleaded guilty to misdemeanor disorderly conduct in another case. He had been accused of shouting profanities and trying to pull away as police arrested him at a Cincinnati bar in 2011.
