Mumford & Sons have postponed three upcoming live shows so that bassist Ted Dwane can undergo surgery for a blood clot in his brain. Dwane has been hospitalized since Monday (June 10), the group revealed via their website on Tuesday (June 11).

"Our friend and bandmate Ted has been feeling unwell for a few days, and yesterday he was taken to a hospital to receive emergency treatment," the statement reads. "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 group have postponed concerts that were scheduled for Dallas on June 11, Woodlands on June 12, and New Orleans on June 13. They plan to announce the re-scheduled dates as soon as possible. Tickets already purchased for the original dates will be honored at the re-scheduled dates.

The group are on the road in support of last year's album 'Babel.' Their tour is expected to resume on Saturday (June 15) with an appearance at Bonnaroo. According to their statement, they have no plans to cancel or postpone any other dates of the current tour.
