Gregg Allman reportedly checked himself into a hospital on Monday, a day before canceling three shows, according to The Oregonian. While no details have been released as to why Allman decided to check himself in, his show in Seattle scheduled for tonight is cancelled and his July 5 show in Spokane, WA has been postponed, the venues announced.

Peter Dammann, the Waterfront Blues Festival artistic director, recounted the story to The Oregonian. “This morning I called up his agent and said, ‘What’s going on?’ They said, ‘We’re evaluating, we’ll get back to you.’ A couple hours later, I got a note from management that said, ‘We’re canceling the whole tour.’ They didn’t give us any specifics on what’s happening with Gregg.”

This is another chapter in a long line of health issues for Allman this year. He previously had to pull out of the Allman Brothers Band’s Beacon run due to a battle with bronchitis and also injured his wrist during the band’s set at Wanee, forcing additional postponements.

Along with his scheduled solo gigs, Allman also has several appearances with the ABB remaining including slots at the Peach Music Festival, Lockn’ Festival and the remaining Beacon Theatre gigs in October.
