Mumford & Sons bassist Ted Dwane has undergone emergency brain surgery.

According to a statement released on the band's official website, the English rocker had a blood cot in his head:

"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."

The band was forced to postpone three shows - two in Texas and one in New Orleans - but has stated that they do not intend to postpone any others: "We have no plans to cancel or postpone any other appearances along this current tour."

The other members ended the statement on a touching note: "We're all wishing Ted a speedy recovery. Much love, Mumford & Sons."
