George Jones continues to deal with health problems, which have forced him to cancel a scheduled concert for Friday (Nov. 2) at a Minnesota casino. The Shooting Star Casino in Mahnomen released a statement announcing that George, who recently turned 81, was stricken with a virus and had to cancel the show, according to the Associated Press.

George previously had to cancel a performance at the same venue in April, as he was recovering from an upper respiratory infection. George has apologized to his fans for the cancellation and the casino notes that there are no plans to reschedule. Ticket buyers will receive a refund.

There has been no further word on George's condition from his publicist in Nashville.
