A Minnesota casino says country star George Jones is ill and has canceled a concert scheduled this week. Jones was scheduled to perform Friday at Shooting Star Casino, Hotel and Event Center in Mahnomen.

That concert had been rescheduled from April when the singer needed more time to recover from an upper respiratory infection. Shooting Star released a statement from Jones' management team, saying the 81-year-old performer has a virus and is being treated by doctors.

Jones apologized to fans for the inconvenience. Shooting Star says there are no plans to reschedule the performance.

We certainly wish the best for George's recovery. I did a story a while back about my personal experience with him.
