Elton John has been forced to cancel three upcoming shows in Las Vegas after being hospitalized for a “serious respiratory infection,” according to a message on his Web site.

The 65-year-old musician developed an infection Sunday and was taken to L.A.’s Cedars-Sinai Medical Center Wednesday, according to statement. He was advised to rest for seven days to “prevent any damage.”

John has been performing his “Million Dollar Piano” show at the Colosseum at Caesars Palace since September. He last performed at a concert Sunday, where he dedicated his performance of “Don’t Let the Sun Go Down On Me” to the late Bee Gee Robin Gibb.

He also canceled shows in February because of food poisoning.

In the statement, John said it “feels strange not to be able to perform” the shows, adding that he would return to Caesars in October.

“All I can say to the fans is sorry I can't be with you,” he continued. “I hope to see you soon at this wonderful theatre at Caesars Palace.”
