Elton John's website announced on Tuesday, July 9 that he has postponed his summer tour because of appendicitis.
"Sir Elton is currently undergoing a course of intensive antibiotics and is expected to undergo surgery in the U.K. in the coming weeks, once doctors can be confident they have sufficiently reduced toxins within the inflamed appendicitis site," a statement on his website read.
The 66-year-old was scheduled to play a show in London's Hyde Park on Friday, but later notified doctors that he felt ill.
"Elton is incredibly disappointed to postpone these tour dates," a spokesman added.
According to John's website, he is still scheduled to perform a 28-date 2013 tour which ends on December 18th.
