Sum 41’s Deryck Whibley was randomly attacked last week in Tokyo and ended up in the hospital. Now the band decided to cancel the remainder of the tour so Deryck could get better and get medical attention for his slipped disk. Can’t really be playing on the Warped Tour when injured, so this news isn’t really that surprising.

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.

Whibley’s condition has not improved. Knowing that they are unable to deliver their signature high energy show, Sum 41 made the tough decision that a break is needed while Deryck begins rehabilitation for the slipped disk.

“Being a part of the Warped Tour this summer meant a lot to us. We haven’t toured in two years and the bands, the crowds and the entire Warped Tour crew have been amazing to us,” said drummer Steve Jocz late last night. “We were excited to be back in front of our fans and are very disappointed that we have to pull off the tour. We know that it would be more frustrating for the fans if we can’t give it our all. Deryck is doing everything he can to get himself better and we’re there for him.”

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
August 14, 2010 – Quincy, WA
August 15, 2010 – Portland, OR

Whibley is expected to make a full recovery with the necessary treatment and rest. The band will be back out on the road again in Europe at the end of August.
