Bob Seger announced Tuesday that due to an “urgent medical issue concerning his vertebrae,” he’ll have to postpone his upcoming tour dates.

That includes his performance at the Pepsi Center, which was scheduled for October 26.

“Hoping to be back out on the road very soon,” Seger said in a news release.

The rescheduled dates will be announced when they’re available, and the tickets you already have for the Pepsi Center show will be honored at the new date.

Get well soon, Bob!
