they were supposed to visit for the first time Mexico, Brazil, Chile and Argentina. In late September, the band was set to return to Australia, playing the new Soundwave Revolution Festival dates, making up for the cancelled Australian dates in February, though on August 9, 2011, it was announced that the Soundwave Revolution Festival would be cancelled following headliners Van Halen pulling out and the organizers failing to close a deal with a second headlining band to appear on the festival, later confirmed to be Aerosmith. On August 23, 2011, it was announced on the band's official website that following Deryck Whibley's back injury on August 13, which forced the back to already cancel their US and Canadian dates in August, the band would be indefinitely postponing all upcoming tour dates for 2011, due to Deryck undergoing a treatment for his medical condition.
