Coldplay singer Chris Martin is suffering from a "serious lung infection" the band has announced, forcing them to cancel eight shows in Rio de Janeiro and São Paulo in Brazil.

In a statement shared on Coldplay's social media accounts the band said they would postpone shows in Rio de Janeiro and São Paulo until early next year and are "optimistic" that Martin will recover after a break.

They had been due to play eight shows in Brazil between 11 and 22 October as part of their Music Of The Spheres world tour.

"With deep regret, we've been forced to postpone our upcoming shows in Rio de Janeiro and São Paulo until early 2023," the band said.

"Due to a serious lung infection, Chris has been put under strict doctor’s orders to rest for the next three weeks.

"We’re working as fast as possible to lock in the new dates and will follow up with more information in the next few days.

"To everyone in Brazil who was looking forward to these concerts, we’re extremely sorry for any disappointment and inconvenience, and we’re so grateful for your understanding at this challenging time where we need to prioritise Chris’ health."

Following the Brazil shows, Coldplay are due to start a run of 10 shows in Buenos Aires, Argentina, on 25 October.

These shows are still scheduled to go ahead, according to details on the band's website.
