If you were hoping to see Gregg Allman live in concert this summer, you're going to have to wait.

Gregg Allman is apologizing to his fans who were hoping to see him out on tour this summer. The southern rocker and former leader of The Allman Brothers says he has a lingering respiratory infection that's keeping him from touring.

He was supposed to kick off the tour tomorrow in Sturgis, but according to a statement, Allman is seeking treatment at an undisclosed medical facility which will be followed by four to six weeks of bed rest. That being said, he still wants to get out on the road this fall to promote his first studio album in more than a decade called "Low Country Blues".

Allmann most recently played a benefit with several other music stars to raise money and awareness for Hepatitis-C, from which Allmann suffers. Allmann had liver transplant surgery last year and he is still recovering, which makes this latest setback that much more alarming.

Gregg Allmann was also supposed to start work on a new memoir. No word on if that will be pushed back as well, or if this latest rest period will be used as a jumping off point to get that project started.
