Bob Seger has been forced to postpone a series of upcoming dates on his Runaway Train tour, including a sold-out show in Atlanta scheduled for Saturday.

The legendary singer said Tuesday afternoon that his doctor has ordered him to attend to an “urgent medical issue” concerning his vertebrae.

Seger, 72, performed at a sold-out show in Pittsburgh last week, but postponed his Sept. 30 concert in Columbus.

Rescheduled dates will be announced soon; previously purchased tickets will be honored at the new dates.
