Former Miami Dolphins offensive lineman Jonathan Martin was charged Tuesday with threatening two former teammates who had harassed him in the NFL and with threatening his former prep school classmates, Los Angeles County prosecutors said.

Martin pleaded not guilty to four felony counts of making criminal threats and a misdemeanor charge of carrying a loaded firearm, district attorney's office spokesman Greg Risling said.

A post on Martin's Instagram page last month showed a shotgun and referred by name to the private Harvard-Westlake prep school in Los Angeles that he once attended.

The post also included mentions of the Instagram usernames of former Dolphins players Richie Incognito and Mike Pouncey and said suicide and revenge were the only options for a victim of bullying.
