Rockers Off! have been forced to scrap a series of U.S. dates to allow frontman Keith Morris to fully recover after slipping into a diabetes-related coma last month (Jan13).

The former Black Flag frontman passed out after missing lunch on his way back from the Big Day Out festival in Australia.

A post on the group's website reads, "Sadly, we have to cancel our west coast tour due to illness. Refunds are available at point of purchase. Thank you for your understanding. We look forward to performing in these cities in the near future."

Speaking to Rolling Stone earlier this month (Feb13), Morris admitted he was still feeling ill after his health crisis.

He said, "I came back, hung out with my girlfriend, and the whole idea was that we were going to do what grown-ups do - go take a nap and go get something to eat. I should have eaten first.

"I passed out... and went into a diabetic-induced coma. So I'm kind of like the T-shirt that's been sitting in the dryer for three days."
