Merle Haggard has been hospitalized with an undisclosed illness, forcing him to scrap a concert in Georgia at the last minute on Tuesday.
The musician was taken ill shortly before his scheduled slot at the Macon City Auditorium and promoters abruptly announced the show wasn't going ahead minutes before the Okie from Muskogee hitmaker was due on stage.
Haggard's tour manager, Frank Mull, reveals the singer has felt sick since leaving his home in California last week.
Promoters have also scrapped his gig in Columbus, Georgia on Wednesday as he recuperates, and he is next due on stage in Kentucky on Thursday.
It's not the first time the musician, who underwent surgery for lung cancer in 2008, has fallen sick in the last year - in August he scrapped a gig in Texas when he was hospitalized with another unknown ailment.
