Suspended Dallas Cowboys defensive end Greg Hardy has reportedly filed his appeal, asking for a neutral arbitrator. On Wednesday, the league announced it was suspending Hardy for 10 games after an investigation found he had violated the personal conduct policy in relation to a 2014 domestic-violence case. According to NBC Sports, the appeal of that suspension was filed on Friday. In suspending Hardy, Commission Roger Goodell cited "sufficient credible evidence that Hardy engaged in conduct that violated NFL policies in multiple respects and with aggravating circumstances." His case was dismissed by a North Carolina state court in February after his accuser refused to cooperate. Fox Sports
