Listen to Mumford & Sons on iHeartRadio

Mumford and Sons bassist Ted Dwane is set to return to the stage this weekend. 

BBC News says the British rockers have confirmed that Dwane -- who underwent emergency surgery earlier this month to remove a blood clot on his brain -- has recovered enough to join his bandmates for their headlining set at Glastonbury. Mumford and Sons are scheduled to close out the massive U.K. festival Sunday night. 

Glastonbury officially gets under way today, although the main performers -- including the Mumfords' fellow headliners Arctic Monkeys and the Rolling Stones -- won't take the stage until Friday.  The full schedule is available at
