These shows have already been rescheduled to the end of the tour and the intinerary now starts May 11 in Englewood, Colo.
"Just wanted to give everyone a heads up, we are planning on this being the biggest and best Fall Out Boy show that we could possibly have. Unfortunately, because of some personal issues we had to delay the tour a few weeks," Fall Out Boy bassist Pete Wentz said.
"The shows from the earlier part of the tour will be rescheduled to the end but all tickets will be honored for all moved shows. Again we apologize. Our fans really mean the world to us and I promise the wait will be well worth it."
The only concert that could not be rescheduled due to routing conflicts is the Sacramento date.
Ticket holders for the Sacramento show can refund their tickets and can also buy tickets for the concert in Concord, Calif., at point of purchase.
Tickets may also be exchanged at Concord box office night of show for comparable price level, subject to availability. Refunds for all rescheduled shows will be given at point of purchase.
