Rolling Stones drummer Charlie Watts may have to sit out the band’s rescheduled U.S. leg of their No Filter Tour this fall.

A spokesman for Watts, 80, confirmed that it is “unlikely” the drummer will be able to join the 13-date tour. Watts, who joined the Stones in 1963, is recovering from an unspecified medical procedure.

“Charlie has had a procedure which was completely successful, but I gather his doctors this week concluded that he now needs proper rest and recuperation,” his rep says in a statement. “With rehearsals starting in a couple of weeks it’s very disappointing to say the least, but it’s also fair to say no one saw this coming.”

Watts wasn’t thrilled by the decision, but says that this is what’s best for his health and the band.

“For once my timing has been a little off. 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,” he explains. “After all the fans’ suffering caused by Covid I really do not want the many RS fans who have been holding tickets for this Tour to be disappointed by another postponement or cancellation.”

Watts said his “great friend” Steve Jordan will be his No Filter Tour understudy. Jordan says that, while he’s looking forward to rehearsing with Mick JaggerKeith Richards and Ronnie Wood — he’s hoping Watts recovers in time to join the trek.

“No one will be happier than me to give up my seat on the drum-riser as soon as Charlie tells me he is good to go,” says Jordan, who previously has collaborated with Richards on all of Keith’s solo albums.

The No Filter Tour starts September 26 in St. Louis.
