Mumford & Sons have been forced to cancel their shows this week after their bassist, Ted Dwane, was hospitalized with a blood clot in his brain.

Dwane had reportedly told the band he was not feeling well over the weekend, and was rushed to the hospital Monday. There, scans revealed a blood clot had formed in his skull and would require surgery.

The band wrote in a statement, "Our friend and band mate Ted has been feeling unwell for a few days, and yesterday he was taken to a hospital to receive emergency treatment. The scans revealed a blood clot on the surface of his brain that requires an operation. Ted is receiving excellent care and we are being assured that he will recover quickly from surgery. 

 "Sadly we have to postpone three upcoming headline shows planned for this week... All dates will be rescheduled and will be announced as soon as we can... We have no plans to cancel or postpone any other appearances along this current tour. 

"We're all wishing Ted a speedy recovery."
