Carolina Panthers defensive end Greg Hardy pleaded not guilty on Tuesday to charges stemming from an early-hours altercation with an ex-girlfriend in May. The Charlotte Observer reported that Hardy arrived at Mecklenburg County Courthouse wearing a dark suit and Panthers-colored black and blue tie. He is charged with communicating threats and assaulting a female. The domestic violence charge could lead to a 60-day jail sentence. Following his arrest, Hardy turned over 10 legally owned guns that were in his home at the time of the incident. In a protective order request, Hardy's accuser claimed Hardy "threw me onto a couch covered in assault rifles and/or shotguns." Source: NFL.com
