Paul McCartney has been hospitalized. The 71-year old legend has reportedly checked into an undisclosed Tokyo facility for treatment for an unnamed virus.

What was originally believed to be a minor ailment that merely postponed one of his concerts at Tokyo's National Stadium last week has resulted in the cancellation of his week-long Japanese tour and next week's show in Seoul, South Korea. McCartney is still scheduled to bring his 'Out There' tour to the U.S. for 19 dates beginning in mid-June, but this new development could possibly put the tour's fate in doubt.

There has been no official confirmation from McCartney's people on the subject, and the most recent update to his website was the announcement of the postponement of the first two Tokyo shows. However, U.S.A. Today cites the Sankei Sports newspaper as breaking the news and offers the above video. Fans have already reportedly gathered outside his hospital to show support.
