Mosaic's Leader Collapses Backstage!

During last night's Top Pop taping, Josh Huslig of Mosaic collapsed backstage, clenching his gut in extreme pain. He was taken to a hospital via ambulance immediately.

From how it looked, there's a good chance his appendix burst, but I'm certainly no doctor. One thing's for sure, if it was his appendix, a kidney stone or possible food poisoning, there's a big chance he won't be able to perform any time soon. What will Mosaic do without their bass tenor?
