According to a report from Reuters, the 50-year-old singer has been admitted to a hospital in Munich, for neurosurgery. The next leg of U2's 360 tour is supposed to kick off on June 3 in Salt Lake City.
"Bono will spend the next few days there, before returning home to recuperate. Once his condition has been assessed further, a statement will be made regarding the impact on forthcoming tour dates," a spokesperson said.
It's unknown at this time if the surgery or the injury will disrupt the band's summer touring plans, which are running through August.
