Paul McCartney has been hospitalized.

A virus infection forced the former Beatle to cancel his Japan tour and South Korea concert. The Sankei Sports newspaper reports that McCartney, 71, was admitted to a hospital when the infection worsened. When contacted by USA TODAY, McCartney spokeswoman Perri Cohen declined to comment or confirm his hospitalization.

On Tuesday, Cohen said in a statement that the rock veteran "is still not feeling better and this cancellation is unavoidable. He was hoping to be better, but the doctors have ordered him complete rest. Paul has been extremely moved by the messages from his fans and is upset to be letting them down."

On Wednesday, after McCartney's May 28 concert in Seoul was called off, he issued his own statement through the show's organizers: "I was really looking forward to visiting and playing in South Korea for the first time and I'm sorry to be letting fans down. I'm very disappointed by this and hope to be able to visit soon."

His Out There tour is scheduled to resume June 14 in Lubbock, Texas, with stops in Minneapolis on August 2, Dallas, New Orleans, Atlanta, Chicago and Nashville, and wrap up Aug. 14 at Candlestick Park in San Francisco, the site of The Beatles' last official concert in 1966.
