If you were looking forward to seeing U2 in concert at Soldier Field this summer, prepare for disappointment.
The band postponed the entire North American leg of its world tour after front man Bono underwent emergency surgery for a bad back.
Bono left a German hospital Tuesday and will need at least eight weeks to recuperate.
The Chicago concert was scheduled for July 6. Ticket holders are urged to hold on to their tickets until further information is available, but the new concert dates will not occur until 2011.
U2 manager Paul McGuinness said that Bono "feels like he has badly let down the band and their audience."
"... the most important thing right now is that Bono make a full recovery. We're working as fast as we can with Live Nation to reschedule these dates," McGuinness says.
Sixteen North American shows will be affected, from Salt Lake City on June 3rd to New Jersey's Meadowlands Stadium on July 19th.
Updates will be posted on U2.com.
