McCartney issued a statement, saying, "I'm sorry but it's going to be a few more weeks before we get rocking in America again. I'm feeling great but taking my doc's advice to take it easy for just a few more days. Look forward to seeing you all soon."
McCartney is recovering from a virus that he contracted in May while touring in Japan. His tour was originally scheduled to launch on June 14 in Lubbock; now that launch will take place in Albany, New York on July 5.
According to the Guardian, McCartney's viral infection has been "hard to shake"; he's already canceled four shows in Japan and one show in South Korea.
