Fans have expressed concern for Bruce Springsteen after the iconic musician was forced to cancel further dates on his US tour.

Springsteen, whose 74th birthday falls later this month, cancelled two dates in Philadelphia last month and has now pulled all dates on his US tour throughout September.

His team released a statement explaining that he is currently being treated for peptic ulcer disease.

"Bruce Springsteen and the E Street Band have postponed all performances currently scheduled for September 2023, beginning with tomorrow’s show scheduled for the JMA Wireless Dome in Syracuse, NY," it read. "Mr. Springsteen is being treated for symptoms of peptic ulcer disease and the decision of his medical advisors is that he should postpone the remainder of his September shows."

It added a message directly from Springsteen, which read: "Over here on E Street, we’re heartbroken to have to postpone these shows. First, apologies to our fabulous Philly fans who we missed a few weeks ago. We’ll be back to pick these shows up and then some. Thank you for your understanding and support. We’ve been having a blast at our US shows and we’re looking forward to more great times. We’ll be back soon. Love and God bless all, Bruce."

Peptic ulcers are open sores that develop on the inside lining of your stomach and the upper portion of your small intestine, and can cause symptoms including burning stomach pain, nausea, bloating and heartburn. It can be caused by a bacteria in the stomach called H Pylori, and treatment involves a course of antibiotics and other medication.

Get well soon, Boss!
