Razorlight's plans for world domination were put on hold last week when illness forced the band to cancel their Los Angeles date and a couple of US TV appearances.
Singer Johnny Borrell was diagnosed as suffering from a laryngitis-type infection and banned from singing for two weeks.
Returning early to the UK, it was hoped that Borrell would be back in full voice in time for the band's sold-out dates next month. But a spokesperson announced today that the six-night run has been postponed while the singer rests and recovers.
Razorlight have had a punishing year, seeing them rise from indie obscurity to one of the UK's most feted bands, propelled there largely by the energy and ego of Borrell. The cancelled dates, at Manchester Apollo, Glasgow Academy and London's Alexandra Palace, were to have been the band's biggest to date.
"Johnny ... is determined to recover as fast as he can and promises to make the re-scheduled shows the most memorable rock'n'roll nights of the year," said a spokesperson for the band.
