In what was sad news on Wednesday night, Willie Nelson announced on social media that he has canceled his tour due to a breathing issue.

Willie had 30 upcoming tour dates until the end of November, including his stop at Darien Lake Amphitheater on September 8th for his "Outlaw Music Festival Tour."

It's not 100% clear if the Darien Lake show will in fact be canceled but it's safe to assume a good portion of his shows will be missed for health concerns.

*UPDATE* Willie Nelson WILL still be performing at Darien Lake!

Willie was scheduled to perform at Darien on September 8th with Alison Krauss, Bonnie Raitt and Phil Lesh and Friends.

This is a developing story and will be updated when more information is known.
