The 37-year-old "Avatar" star was ordered on Wednesday to stay away from photographer Sheng Li for six months. Worthington was released on his own recognizance.
Prosecutors say Worthington punched the photographer in the face in a scuffle Sunday in Manhattan's Greenwich Village. They say he told officers he was protecting his girlfriend.
Defense lawyer Stacey Richman told the judge photographers have relentlessly followed Worthington. Earlier, the actor had no comment when he entered Manhattan Criminal Court.
Li was arrested on reckless endangerment, assault and harassment charges. His lawyer says Li shouldn't have been arrested.
