Watts’ spokesman said that while his procedure had been “completely successful”, the drummer had been told by doctors he needs “proper rest and recuperation”.
He said it was “very disappointing” that Watts was unlikely to be able to go back on the road at present, adding that “no-one saw this coming“.
Watts said: “I am working hard to get fully fit but I have today accepted on the advice of the experts that this will take a while.
“After all the fans’ suffering caused by Covid I really do not want the many RS [Rolling Stones] fans who have been holding tickets for this tour to be disappointed by another postponement or cancellation.”
The Stones’ first concert will be in St Louis on 26 September, with dates to follow in Dallas, Nashville and other US cities.
They will be the legendary band’s first performances since the virtual rendition of You Can’t Always Get What You Want during the One World: Together At Home concert in April 2020.
