"Pavarotti is recovering well and his physicians are encouraged by the physical and emotional resilience of their patient," Robson said in a statement. All remaining dates on his 2006 farewell tour have been cancelled, however.

The singer has been plagued recently by a succession of illnesses and injuries, including lower back problems and laryngitis, which have forced him to cancel numerous concerts this year.

Pavarotti, who gave his final opera performance at the Metropolitan Opera in 2004, is in the midst of a worldwide concert tour. The tour was originally scheduled to end by his 70th birthday last October, but he has since said that he expects it to continue for another year or two before ending in Milan, London, Vienna or New York at the Met.

Robson says it is hoped the tenor will recommence his tour in early 2007.
