LONDON — Rolling Stones frontman Mick Jagger will undergo heart surgery this week following the postponement of the band’s North American tour for medical reasons, according to a published report.

The US website Drudge Report, citing unidentified sources, said Mr. Jagger, 75, would undergo surgery this week in New York to replace a heart valve. New York Post’s Page Six website, citing unidentified sources, said the surgery would involve placing a stent in the singer’s heart.

Representatives for Mr. Jagger in the US did not return requests for comment. A spokesman for the British band in London declined to comment on the Drudge Report article.

The band on Saturday announced it was postponing all dates on its tour of the US and Canada to give Mr. Jagger time to receive medical treatment. It did not specify what treatment Jagger needed but said he is expected to make a full recovery.

The North American tour had been scheduled to run from April 20 until June 29.

Mr. Jagger was photographed on Sunday in Miami Beach, Florida on the beach with his current girlfriend, ballet dancer Melanie Hamrick, their young son, and daughter Georgia May, one of his seven adult children.

The British singer has not explained his medical issue but told fans in a tweet on Saturday that he would be “working very hard to be back on stage as soon as I can.”

After a storied sex, drugs and rock ‘n’ roll lifestyle in his earlier days, Mr. Jagger now follows a healthy diet, runs, and works out frequently.

Stents are typically used to prop open arteries that have been cleared of a blockage. — Reuters
