Smith allegedly beat and then stomped on the male victim's head near the corner of Arroyo Parkway and Colorado Boulevard early in the morning on July 4, the prosecutor said per documents obtained by NFL.com.
Smith's attorney, Daniel Rosenberg told NFL Network Insider Ian Rapoport that Smith "has maintained his innocence and will enter a plea of not guilty." Rosenberg said Smith will fight this all the way.
NFL.com reached out to the Raiders for a comment on the matter but the team has yet to give a response.
His arraignment is scheduled on Sept. 29 at the Los Angeles County Superior Court Pasadena Branch.
If convicted as charged, Smith faces a possible maximum sentence of seven years in state prison.
The case remains under investigation by the Pasadena Police Department.
