Sum 41 have been forced to cancel their remaining Warped Tour appearances as well as an upcoming Canadian tour due to frontman Deryck Whibley once again hurting his back. Whibley had to have surgery on his back a few years ago, so he is more prone to injury than most. You can read a statement from the band below by clicking “Read More”.

During yesterday’s show in Boise, Deryck sustained another back injury and we have been forced to cancel the remaining Warped Tour dates and the Canadian run that was to follow.
We hate canceling shows, but Deryck’s well being is our top priority and the best thing right now is to give him time to heal.
Thank you for your understanding. We wish Deryck a quick recovery and look forward to getting back out on the road.
