Willie Nelson has canceled his current tour because of a "breathing problem."
The cancellation includes Friday's scheduled performance at Van Andel Arena in Grand Rapids. Arena officials, in a written announcement, said Thursday that the concert will be postponed to an as yet undetermined date.
The 86-year-old singer apologized on Twitter late Wednesday, writing "I need to have my doctor check out." Nelson had just finished performing with Alison Krauss in Toledo, Ohio, and he was next scheduled to appear Friday in Grand Rapids, Michigan.
He wrote "I'll be back."
Nelson was scheduled to perform Friday, Aug. 9, 2019, at Van Andel Arena in Grand Rapids. The country music star was scheduled to perform with Alison Krauss, and special guest Ida Mae. It was unclear early Thursday whether the performance would continue, just without Nelson.
