Linebacker Jermaine Cunningham is a free agent and any attempts by the former Patriots second-round pick to continue his career may be hindered by discipline from the NFL.

Cunningham pleaded guilty Wednesday to three charges related to a December arrest following a domestic dispute. The dispute started after Cunningham posted photos of a girlfriend’s inner thigh, groin and buttocks on Instagram without her permission, which violates a 10-year-old New Jersey “revenge porn” law that makes it a crime to share such images without the subject’s approval.

NJ.com reports that Cunningham admitted posting the pictures and tagging them with the woman’s name while pleading guilty to a third-degree crime of invasion of privacy and fourth-degree charges of illegally transporting a handgun in the glove compartment of his car and having hollow-point bullets. The gun and bullets were found in Cunningham’s car at the time of his arrest and he was sentenced to probation for a period that will be set at a June hearing.

Cunningham was selected by the Patriots in the second round of the 2010 draft and spent three years with the team before moving on to the 49ers and Jets, who he was playing for when he tore his Achilles before the start of the 2014 season.
