Canadian pop punks Sum 41 have been forced to cancel several forthcoming European tour dates. It is understood that drummer Steve Jocz broke his arm in a car accident. "[He] is unable to get on a airplane to fly to Europe to perform," reads an official statement from the band. "Anyone who knows our band, knows that touring is our life and is the primary reason we play music. We are completely and utterly bummed out and we all wish Stevo a speedy recovery. We want to sincerely apologise to our fans in the cities we can't make it to and we promise to return to them in a few months. We will reschedule any dates that we unfortunately had to cancel in Europe ASAP. See you all soon."The band have recently completed work on their follow-up to 2007's Underclass Hero.
