Four of the five simple assault charges against Chukky Okobi were dismissed at a preliminary hearing Thursday.
The former backup center had been accused of assaulting a group of people who confronted him while he had a heated discussion with his girlfriend.
Defense attorney Bob Del Greco says his client was acting in self-defense after getting jumped by several people. One of the other men involved in the fight was convicted of harassment and fined $100.
The single remaining charge involves Okobi's scuffling with a bar security guard.
The 33-year-old Okobi spent seven seasons in the NFL, six of them with Pittsburgh.
