For the third time this year, health issues have caused Gregg Allman to bow out of several tour dates. Today (July 2), we learn that he is currently in a hospital for an undisclosed illness, leading to the postponement of three concerts -- and one outright cancellation -- in the Northwest.

According to Oregon Live, Allman has been in a hospital since Monday, the day before he was supposed to appear in Boise, Idaho. That show, as well as Saturday's concert in Spokane, Wash. and Sunday night at Portland's Waterfront Blues Festival, will be rescheduled. However, tonight's appearance at Seattle's Woodland Park Zoo will not be made up.

"He decided to cancel the gig tonight in Boise yesterday," Peter Dammann, the artistic director of the Waterfront Blues Festival, said yesterday. "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."

Back in April, a broken wrist forced Allman to pull out of the last two dates on his solo Australian tour. This came a month after his bronchitis caused the postponement of four nights by the Allman Brothers Band at New York's Beacon Theater. Those shows have been re-scheduled for October, as part of the last shows the Allman Brothers will ever play.
