The 411 on 311's upcoming European tour looks grim. Guitarist Tim Mahoney will undergo a hernia operation in LA this week, which will put their October 10-16 European tour on hold.| As of yet, it is unclear whether those dates will be made up at a later date. Mahoney is expected to recover in-full and return for the second leg of their tour which will feature opening act Sugar Ray. (Brandon Barber)
