Reports in the US say that Sir Mick Jagger, the iconic lead singer of the Rolling Stones, is set to undergo surgery this week, to replace a damaged valve in his heart.
At the weekend, they postponed the US leg of their current tour , so that Sir Mick could undergo medical treatment, after he was told by doctors he could not perform.
According to the New York Post's "Page Six" site, Jagger has a damaged valve in his heart, and is set to receive a stent, sparking worries about the veteran musician's health.

He gave up drugs when he met his second wife, Jerry Hall, and rarely drinks alcohol.

He was even spotted on a Miami beach on Sunday, allaying worries that the singer is seriously ill.

Sky Views: The Rolling Stones have still got it They are still a contemporary phenomenon as demonstrated by the scale, expense and popularity of their tour.
But despite being in peak physical condition, the singer has not avoided health problems, and will undergo surgery in a New York hospital this week.
Jagger will reportedly receive a stent, which is a small metal tube that is inserted into the body to open up arteries.
Procedures usually involve inserting the tube into an artery using a small inflated balloon-like device, before it is removed, leaving the stent in place.
Patients often see a quick recovery when getting a stent and can be out of the hospital just 24 hours after the surgery.

If left untreated, a blocked artery or damaged valve could lead to a heart attack, which would have far worse consequences for Jagger.
The US leg of the Rolling Stones' "No Filter" tour was set to begin in Miami in just a few weeks, but has since been postponed.
On Sunday, Jagger told his fans "I really hate letting you down like this... but I will be working very hard to be back on the road as soon as I can."
