British band Mumford & Sons says on its website its bass player Ted Dwane has been hospitalized and is undergoing treatment for a blood clot on his brain.
"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 said it is postponing its next three concerts, but will reschedule them "as soon as we can."
"We're all wishing Ted a speedy recovery," the statement said.
