Former Korn drummer David Silveria has apologised to fans for skipping the band's 20th anniversary tour.

The group is marking two decades since their release of its self-titled debut record in 1994 by heading out on tour and playing the album in full at the shows.

Many fans had hoped Silveria, who left the group in 2006, would rejoin his former bandmates to celebrate the milestone, but the drummer has now confirmed he will not be taking part.

In a message posted on Facebook.com, he writes, "To all the Korn fans around the world, I want to thank you with all of my heart for all of the success. Without the fans Korn would just be a hobby. As we celebrate the 20th anniversary of our debut release, I'm sorry to all the fans that I couldn't be there on tour to celebrate - but that's just the way it goes."

Silveria has never confirmed the reason why he left, but Korn frontman Jonathan Davis previously insisted his colleague had lost his passion for music, telling The Pulse Of Radio, "David was there to write beats but he wasn't really there - he really didn't like playing drums. The first two albums, I think he really enjoyed playing and then after that, he just lost his love for playing drums. It happens."
