Denver Broncos linebacker Jonathon Cooper pleaded not guilty to all charges related to his domestic violence case in a Colorado courtroom Monday. A jury is scheduled to begin Nov. 10, with a pretrial hearing set for Oct. 30.Cooper, 28, was initially arrested June 4 after police were called to his apartment following an altercation with his then-girlfriend. He was charged with domestic violence and misdemeanor criminal mischief. The charges were later upgraded to include felony second-degree assault by strangulation after a further review of the incident that included a report from a nurse who examined the woman the night of the initial incident. The nurse wrote in her report at the time the woman suffered “serious bodily injury” that was consistent with “strangulation with hypoxia” and “traumatic brain injury,” according to an arrest affidavit.He was arrested a second time June 11 on a charge of violating a protection order put in place after the initial incident.At his arraignment Monday, Cooper pleaded not guilty to all five charges — second-degree assault by strangulation, third-degree assault by knowingly or recklessly causing injury, criminal mischief, violating a protective order and harassment.His trial is scheduled to begin Nov. 10 and end Nov. 13. The Broncos are on a bye during that window.
