The jury trial for Hardy had been set to begin in Charlotte after he was accused of assaulting his former girlfriend , Nicole Holder , and threatening to kill her . The league 's probe , which involved numerous interviews with witnesses and experts , concluded that Hardy violated the NFL 's personal conduct policy by using physical force against Holder in at least four instances . 'The net effect of these acts was that Ms. Holder was severely traumatized and sustained a range of injuries , including bruises and scratches on her neck , shoulders , upper chest , back , arms and feet , ' Goodell wrote . 'The use of physical force under the circumstances present here , against a woman substantially smaller than you and in the presence of powerful , military-style assault weapons , constitutes a significant act of violence in violation of the Personal Conduct Policy .

Prosecutors said when Holder last spoke with them in November , she told them that she 'did not want to participate in another trial . ' Holder had already reached a civil settlement with Hardy , prosecutors said . Hardy may appeal the NFL 's decision within three days . 'You must have no further adverse involvement with law enforcement and must not commit any additional violations of league policies , ' Goodell wrote .
