Sir Rod Stewart needs surgery to repair an ankle injury.
The 'Maggie May' singer has to go under the knife again to have his ankle fused after he was left struggling to walk following his knee replacement back in January.
He told the Daily Mirror newspaper: "First of all it was my knee as I played football all my life. I am suffering for it now.
"My knee got fixed with a replacement and then the ankle did not know what was going on. It was crooked. So I have had to have an ankle fusion.
"So when this is all done I should have a nice straight leg and I should be able to run. My leg has been caused by playing on awful pitches in Los Angeles. They are bone dry."
After his knee surgery at the start of the year, the 75-year-old star had returned to the stage before the coronavirus lockdown, and was set to head out on tour.
In February, his wife Penny, 49, gave a positive update on his health and insisted "there is no stopping him".
She said: "He has just done two private shows in Florida and he said, ‘My knee is better now than it has ever been’.
"He said he was running sideways and it has all been sorted. He is like a masterclass of knee replacement – there is no stopping him.”
Despite the pandemic, Rod has a US tour in the books for next summer, and an Australian leg currently set for March and April 2022.
Meanwhile, Rod revealed last year that he'd beaten prostate cancer after a secret battle with the disease.
And Penny - who has Aiden, nine, and Alastair, 14, with Rod - subsequently admitted it was a "terrible time" for their whole family.
The model - who has been married to the music star since 2007 - said: "It was awful, such a terrible time. It was the shock of it.
"Rod isn't like one of those men who will never go to the doctor. He has more check-ups than anyone I know.
"And yet, when they picked it up, it wasn't just contained in the prostate. It had come through - but, thankfully, not to the point where it spread throughout his body."
