The reason for The Rolling Stones' delayed North American tour has been revealed, with frontman Mick Jagger set to receive heart surgery very soon.

The 75-year-old singer will undergo an operation to replace a valve, sources confirmed to Rolling Stone, with the treatment looking likely to take place this week.

The British star will need weeks to recuperate after the procedure, which has resulted in the Stones postponing the US leg of their No Filter tour, which the band confirmed days ago.

"Mick has been advised by doctors that he cannot go on tour at this time, as he needs medical treatment," the statement said.

"The doctors have advised Mick that he is expected to make a complete recovery so that he can get back on stage as soon as possible. "

Following the announcement, father-of-eight Jagger apologised for the delay, telling fans he "hated letting them down".

"I'm so sorry to all our fans in America and Canada with tickets. I'm devastated for having to postpone the tour but I will be working very hard to be back on stage as soon as I can."

The tour was due to kick off in Miami on April 20, before travelling across the US for 17 shows and finishing up in Oro-Medonte, Canada on June 29.

"We’ll miss you over the next few weeks, but we’re looking forward to seeing you all again very soon," Stones guitarist Ronnie Wood tweeted to fans.

Rescheduled dates are expected to be announced soon, with existing concertgoers told to keep hold of their tickets.
