Jonathan Martin was in a California court on Tuesday afternoon where he pled not guilty to four felony counts of making criminal threats and one misdemeanor count of carrying a loaded firearm in a vehicle.
Martin is due back in court for a preliminary hearing on April 25.
As we previously reported, Martin posted a photo on social media last month of a shotgun and ammunition and then called out former teammates Mike Pouncey and Richie Incognito.
He was eventually tracked down by cops, detained and brought to a hospital for a mental evaluation.
The former Miami Dolphins player also tagged Harvard-Westlake High School, which went into an emergency lockdown as a response. The high school has since sought a restraining order against Martin to protect the faculty.
