A grand jury laid the smack down on Jersey Shore star Ronnie Ortiz-Magro Thursday.

24-year-old Ortiz-Magro was indicted in Ocean County, New Jersey, for his involvement in a fight that occurred during the first season of the MTV hit. Charged with one count of third-degree assault, Ortiz-Magro faces up to five years in state prison, TMZ reports.

Stephen Izzo, who was on the receiving end of Ortiz-Magro's blows, has a pending lawsuit against the Jersey Shore star, the show's producers and MTV.

Though the incident occurred on September 4, 2009, sources tell TMZ that the charges were delayed because both sides were attempting to reach a plea agreement.
