Mumford & Sons have postponed their show scheduled for Monday at the Cricket Wireless Amphitheater in Bonner Springs.
The band also canceled its performance Saturday at the Bonnarroo Music & Arts Festival in Tennessee.
A new date for the Bonner Springs show will be announced soon, promoters said, so fans are advised to hold on to their tickets.
Fans can also get a refund where they bought the tickets.
Earlier this week, bassist Ted Dwane was treated for a blood clot on his brain. He has been released from the hospital and has returned home. The band released a letter to its fans addressing Dwane and the shows.
“It is with great joy that we can announce that Ted has been discharged from hospital and is on the road to a full recovery. The surgery went well, and the excellent medical team helping him are very pleased with his progress. He has been nothing short of heroic in how he has handled the whole ordeal, and now it has been medically proved that he does indeed have a brain.
“Today, however, also marks the end of our Summer Stampede Tour. We were hoping to have made it out by Bonnaroo this weekend. But it is with sadness that we have to announce the cancellation of our scheduled performances at both Bonnaroo and Telluride Festivals, and a postponement of our show at Cricket Wireless Amphitheater in Bonner Springs, KS. “
It was just announced that Jack Johnson will take over the Mumford & Sons' time slot at Bonnarroo.
