Fall Out Boy have been forced to reschedule their current US tour due to unspecified "personal issues".

The band were due to start their North American tour on April 18 in Charlotte, North Carolina, but it has been pushed back by almost a month and will now begin on May 11 in Denver, Colorado.

Bassist Peter Wentz wrote on his online journal: "Everyone knows (our) tour has been pushed back - no I am not dead (unless this is the replaced robot me writing this), no-one is in rehab.

"Hopefully you know how much we love to tour and want to keep going.

"After some things coming up it is in the best interest of the health of the band and its members to take just a couple of weeks to catch up."
