Slipknot have been forced to cancel their appearances at this weekend's Reading and Leeds Festivals after drummer Joey Jordison broke his ankle.
The band were set to appear on the main stage at Reading Festival on the Sunday (24 August) and Leeds Festival on Friday (22 August).
However a statement issued by the band today has said that Jordison has been advised to rest for four to six weeks due to this injury.
The statement from Slipknot reads: "To Our Fans: It is with huge regret and disappointment that we have been forced to cancel our imminent festival appearances at Leeds and Reading.
"The other night, Joey Jordison broke his ankle and doctors have advised Joey to stay off his leg for 4-6 weeks to prevent further injury or permanent and more serious damage.
"We know you will be hugely disappointed and so are we. Cancelling shows is never an easy decision and we apologize to all our fans, friends and family for not being there to throw down with you."
Both festivals have sold out.
