According to TMZ.com, former KORN drummer David Silveria pleaded "not guilty" earlier this week in an Orange County, California courtroom to a charge of allegedly driving under the influence.

A pretrial date has been set for September.

Silveria told TMZ.com that he had no alcohol in his system when he was arrested for DUI on March 25, claiming that he was taken into custody over a sleeping pill he took the night before.

The 39-year-old musician — who played with KORN for 13 years — said that he took a sleeping pill the night before his arrest to help him with insomnia. When he woke up the following morning, he accidentally rear-ended another car on his way to breakfast in Huntington Beach, California.

Although Silveria says he blew a 0.0 on the breathalyzer at the scene of the accident, the cops decided to arrest him for DUI after being told about the sleeping pill.

Silveria told TMZ.com at the time that he planned to take responsibility for his actions, insisting, "It was an honest mistake."

Silveria recently joined forces with ANYONE members Riz Story and Miki Black in a brand new project called INFINIKA.

David left KORN in late 2006 in order to focus on family life along with running his steak house and sushi restaurant.
