SLIPKNOT guitarist Jim Root was forced to miss the kick-off show of the Rockstar Energy Drink Mayhem Festival in San Bernardino, CA on June 30th due to "serious health issues." The band has released the following statement:

"Jim has been seriously sick for the past two weeks and went to the hospital last week where he was advised that his appendix burst a couple weeks before and that it could have been life-threatening. Jim is at home recovering and is awaiting surgery to have pieces of his appendix removed and hopes to join the tour as soon as he is able. Slipknot will continue to headline the Mayhem festival and all other shows. We refuse to let our fans down and will not miss a single date. We will miss Jim greatly and our thoughts are with him. Jim sends his love to each and every one of our fans."
