Bob Seger and the Silver Bullet Band postponed the rest of their 2017 Runaway Train Tour after the rocker received doctor’s orders to treat a medical issue concerning his vertebrae.

“I’m so disappointed to have to suspend the tour as the band is on a great roll,” Seger said on his website. “It’s a privilege to play for our amazing fans. Hoping to be back out on the road very soon.”
