Sum 41 Cancel South American Tour

Sum 41 have been forced to cancel their upcoming South American tour with Four Year Strong, Attack Attack!, and Pierce The Veil due to front man Deryck Whibley's ongoing medical condition.

The band have released the following statement:

"Sum 41 has indefinitely postponed the remainder of dates on their Screaming Bloody Murder tour for 2011 due to a medical condition Deryck Whibley is currently undergoing treatment for. In order to fully recover, Deryck is under doctor's orders to start a rehabilitation program and to recuperate for the rest of 2011. This will make the cancelation of all upcoming tour dates beginning in South America September 4th through Asia October 18th necessary.

"We are all devastated that our best tour yet has been interrupted." said Drummer Stevo Jocz " Our band lives to be on stage and playing in front of our fans. We never want to let anyone down but the most important thing right now is that Deryck makes a full recovery so we can continue on next year . We’re working as fast as we can to reschedule these dates."
