Rockers Slipknot scrapped a second weekend show on Sunday night (23Aug09) after a band member fell ill.
The masked band's headlining spot at the Pain In The Grass festival in Washington was cancelled on Saturday (22Aug09) after drummer Joey Jordison was hospitalised.
He was expected to take the stage at the Toyota Center in Kennewick, Washington on Sunday, but that concert was postponed when a bandmate fell ill.
The group plans to reschedule Sunday's show.
Reports suggest Sunday's cancellation had nothing to do with Jordison, who was treated for a "severe medical emergency" on Saturday.
