The Rolling Stones have been forced to cancel Saturday's scheduled performance in Hanging Rock, Australia, after vocalist Mick Jagger developed a throat infection.

Jagger is reportedly under strict doctor's orders to rest his vocal chords for the next few days, which will in turn allow the band to complete their Australian tour.

"The Rolling Stones are incredibly disappointed to cancel the Hanging Rock gig and to disappoint their fans but were left with no other option,” a spokesman for the band says. The group also confirmed, via Twitter, that rescheduling the cancelled show was "not logistically possible."

The group's current Australian tour is comprised of shows that were originally scheduled to take place this past March. But following the tragic passing of Jagger's long-time girlfriend L’Wren Scott, the band scuttled touring plans to allow Jagger time to grieve and heal.

The Rolling Stones current Australian tour kicked off on Oct. 25 and is due to resume in Sydney on Wednesday Nov. 12. Jagger isn't the only one ailing, by the way. This leg of the '14 on Fire' tour also finds the band without Bobby Keys. The longtime sax player was placed on medical leave and ordered to “take it a bit easy for the next month.”
