Ronald Gasser, who shot and killed former Jets RB Joe McKnight, pleaded not guilty on Monday to a second-degree murder charge, according to the Associated Press.
The 55-year-old Gasser, who had initially been charged with manslaughter, was indicted last week, NBC Sports reported.
McKnight, who was 28 years old, was killed in a shooting in Louisiana in December.
A witness said an argument took place between McKnight and the shooter before the shooter opened fire multiple times.
McKnight played for the Jets from 2010 to 2012. He was drafted by the Jets in the fourth round (112th overall) of the 2010 NFL Draft. On Monday night, the Jets plan to have a moment of silence to honor McKnight before kickoff.
The Jets honored McKnight with a moment of silence prior to their first game after his death.
