The Santa Clara County District Attorney's office says Smith is expected to surrender later this month.

The 24-year-old Smith is on an indefinite leave from the team while undergoing treatment for substance abuse following a DUI arrest Sept. 20.

The 49ers issued a statement Wednesday saying, "We recognize the serious nature of this situation, as does Aldon."

Last month, Smith and former teammate Delanie Walker were named in a lawsuit filed in Santa Clara County Superior Court by a Northern California man who said he was shot at a party at Smith's house on June 29, 2012.
