After undergoing numerous tests, the 65-year-old performer's rep released the following statement:

    "Those tests resulted in the attending physician recommending that Elton not perform any concerts for approximately seven days with complete rest and antibiotic treatment to cure his respiratory infection and prevent any damage."

The "Rocket Man" singer became ill following a Vegas performance on May 20. He's currently performing in Sin City at The Colosseum for his "Million Dollar Piano" concert dates, however his current illness has forced him to cancel several shows.

John released the following statement to his fans:

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

I'm sure they'll understand, Sir Elton. Get well soon!
