Elton John has postponed his upcoming summer tour, including a planned Hyde Park date later this week, after being diagnosed with appendicitis.
A message on his website states that John fell ill recently on the European leg of his tour and sought out medical attention in Britain. "A diagnosis of appendix abscess surrounding retrocaecal appendicitis has been confirmed," according to the site.
John is currently receiving antibiotics and is expected to undergo surgery in the coming weeks. Doctors have advised him to postpone several forthcoming shows, including a headline date at Hyde Park in London on Friday, as well as dates in Italy, Germany, Spain, France and Monaco.
A spokesperson said John plans to be on the mend by the time he is scheduled to play Bestival on Sept. 8 and the iTunes Festival on Sept. 12, both in the U.K. From Sept. 18 through Oct. 12, he is slated to perform his Las Vegas show at The Colosseum at Caesars Palace, and in December he'll visit Russia, Sweden, Norway, Belgium Czech Republic and Germany.
"Elton is incredibly disappointed to postpone these tour dates," the statement said. "To know that he made such super-human efforts and continued to perform to thousands through his illness only confirms his dedication to his European fans. He is eager to be back on top form and return to play the remaining shows starting in early September 2013."
John is expected to release his Capitol Records debut, titled "The Diving Board," in September. In April, he previewed three of the songs at the famed Capitol Studio, telling audience members he and writing partner Bernie Taupin used Bob Dylan's 2006 release "Modern Times" as the "template" for the album.
"I want to try to make records like that. (Dylan) is the person we aspire to be," he said. "The advantage of having Bernie is that he's always been a cinematic writer and working with him is still as exciting as it was in 1967."
