Sir Rod Stewart says he is devastated to have to cancel a series of US concerts, blaming lingering flu for the decision.
It affects four shows in Nevada, along with a further two in California, which he plans to reschedule.
They were due to take place over the next eight days.
"So sorry my friends. I'm devastated and sincerely apologise for any inconvenience to my fans. I'll be back on stage and will see you soon," he wrote in a message on Instagram.
Sir Rod, 80, has been struggling to recover from flu and this week had already cancelled two concerts at Caesars Palace, Las Vegas.
On Wednesday, he disclosed that his doctor had "ordered" him to take "a bit more rest".
The star is in the midst of his epic One Last Time Tour.
Sir Rod, who was recently put on vocal rest, is due to play the legends slot at Glastonbury later this month.
In May, he was presented with a lifetime achievement award at the American Music Awards (AMAs).
In a sign of how seriously the singer takes his health, last month he was also spotted in Italy attempting to avoid conversations to preserve his voice.
He wore a message attached to a lanyard which read: "Sorry. Cannot talk. Having vocal rest."
In 2024, he promised he would not retire but confirmed his 2025 European and North American shows would bring an end to his "large-scale world tours".

The performer, best known for songs including Da Ya Think I'm Sexy?, Every Beat Of My Heart, and Maggie May, said he plans to focus on more intimate venues instead.
Sir Rod has faced other health challenges in the past.
In May 2000, he was diagnosed with thyroid cancer and had surgery. In 2017, he underwent successful treatment for prostate cancer.
