Masked heavy metal giants Slipknot have been forced to cancel all tour dates for the remainder of this month and next after drummer Joey Jordison was "taken to hospital for health reasons", according to the band's website.

This announcement followed a story earlier in the week that Joey was expected to make a full recovery in time for the band to resume their US tour on Sunday. Obviously things are more serious than first thought. We'll bring you more news as we have it, but in the meantime we wish Joey a speedy recovery.

Below is a video of Slipknot frontman Corey Taylor informing the Seattle crowd about the first show cancellation last Saturday (22 August).
