Terrell Suggs -- Pleads Not Guilty In AZ Car Crash Case

NFL superstar Terrell Suggs just pled not guilty to all charges in his Arizona car crash case ... formally denying he left the scene of an accident last month.

TMZ Sports broke the story ... the Baltimore Ravens star was arrested on March 4th and later charged with 2 misdemeanors -- driving with a suspended license and failure to notify after striking a fixture.

Suggs admitted to striking a wall while driving in a shopping center late at night. He claims he did NOT flee the scene but rather went to a nearby Mexican restaurant to call someone to pick him up.

If convicted of the suspended license charge, Suggs could face up to 6 months in jail. The failure to notify charge carries a lighter sentence ... up to 30 days in jail.

He's due back in court in May.
