The band were due to be performing on the Kerrang! Tour alongside New Found Glory, letlive. and While She Sleeps starting on February 4.
"I feel really terrible about letting down the fans," says Deryck. "I injured my back and the doctors are saying that I could be in a wheelchair. So, as much as I wanted to be able to do it, I've got to look at reality, and for the first time I've got to listen to somebody else and not just myself. We're all really upset about this; we've had such a great relationship with our UK fans. We were really looking forward to thistour."
The band will be replaced by The Blackout for the eleven dates in February, which are:
