Sum 41 has been forced to cancel their return to the Vans Warped Tour. The band was a crowd favorite, playing over 20 dates during the seven week summer tour that took them to cities all over the United States and Canada. The band had taken leave to play Summer Sonic festival dates in Japan and were expected to resume their spot on the Vans Warped Tour this week. Unfortunately, lead singer Deryck Whibley was attacked in a random unprovoked incident in Japan last Thursday night which aggravated a previous slipped disk injury that he sustained in 2007. After seeking medical attention, Deryck and band mates Steve Jocz, Cone McCaslin and Tom Thacker went on to play as part of the festival in Osaka and Tokyo.
Sum 41 will not perform at the following Vans Warped Tour dates:
August 11, 2010 — Pomona, CA
August 12, 2010 — Marysville, CA
August 13, 2010 — Boise, ID
