Sum 41 Cancel Tour Due to Deryck Whibley's Back Injury

Sum 41 have been forced to cancel their Kerrang! Tour in the UK due to health issues with lead singer Deryck Whibley, who, doctors are warning, "could be in a wheelchair" because of a back injury.

"I feel really terrible about letting down the fans," Whibley said in a statement on the Canadian pop-punkers' site.

"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 this tour."

Whibley has suffered from back problems for a number of years. In 2007, Ultimate-Guitar reported that the band's 'Strength in Numbers' tour of Eastern Canada was curtailed after doctors discovered he was suffering from a herniated disc. Then he was attacked in a Japanese bar in 2010 which left him with a slipped disc. Despite being advised to not perform, the group carried on with their Japanese dates before the singer collapsed mid-performance in Sendai. Last summer Whibley's back problems flared up once again causing Sum 41 to nix remaining Warped Tour dates. Whibley was also hospitalized in Australia with severe pneumonia in 2011.

The singer must be screaming bloody murder with all the maladies. However it's rather appropriate as the band is still on their 'Screaming Bloody Murder' world tour.

As for their future dates, Sum 41 is still slated to mount a Far East and South Asian tour in Tokyo on March 31. The jaunt sees them visit China, Taiwan, Indonesia, Singapore and Malaysia. The Kerrang! Tour will carry on with the Blackout named as Sum 41's substitute alongside New Found Glory, letlive and While She Sleeps.
