Sticksman Graham Hopkins suffered a seizure on stage at the gig at Los Angeles' House of Blues, according to audience members, who discussed the horrific incident on a Cranberries fansite.

ZombieGuide.com user 'New Zombie' reports, "The drummer had a seizure right on stage. They killed the lights and lowered a screen. He had to be taken by ambulance to the hospital after what seemed like 20 minutes of medical treatment while he was laying on stage."

The website claims O'Riordan's tour has been cancelled because the band do not have a replacement drummer.

Last week (13Jul07), O'Riordan was forced to cancel her Washington D.C. gig after a dental emergency.
