Smith will face a hearing on July 30 to discuss the matter, Los Angeles City Attorney's Office spokesman Frank Mateljan told USA Today Sports by email Tuesday.
"A City Attorney Office hearing is administered by members of the City Attorney's office in lieu of a criminal filing," Mateljan wrote in the email. "Involved parties are scheduled to attend and give their account of the incident. The individuals are then admonished about the applicable laws and given suggestions on how to avoid similar incidents in the future."
Although no action will be taken now, the office reserves the right to file charges up to one year after the April 13 incident.
Smith, 24, has faced a tumuluous year with several off-field incidents. He missed five games after voluntarily checking himself into a substance abuse program, and faces a July 25 sentencing hearing on weapons and DUI charges from two unrelated incidents. He faces the strong possibility of being suspended by the NFL to begin the 2014 season.
Smith has 42 regular-season sacks through his first three NFL seasons since being a first-round pick out of Missouri in 2011. He will turn 25 on Sept. 25.
