Slipknot frontman Corey Taylor had to be carried off stage at a gig in Texas on Tuesday night (10Jul12) after passing out during the final song.
The rocker was performing with the band in Dallas, Texas as part of the Rockstar Energy Drink Mayhem Festival tour and he gave fans a fright during the finale when he suddenly fell to the floor.
Footage filmed at the gig shows crewmembers rushing onto the stage to tend to Taylor, who had fallen unconscious, before picking him up and carrying him backstage.
Taylor later addressed his health crisis in a post on, assuring fans he was just suffering from heat exhaustion and insisting he will be well enough to tackle the band's next gig.
He writes, "Hello everyone. I'm fine - just overheated in Dallas last night. Ready and waiting for Houston! Thank you to everyone for your concerns!"
