Neil Young and Crazy Horse have had to cancel their four-city North American tour due to an injury to guitarist Frank “Poncho” Sampedro’s hand.

“[His] doctor has indicated that Sampedro’s hand requires additional time to heal properly,” said a press release. The band also had to cancel the last seven dates of their European tour earlier this month due to the same injury.

“We are sorry for any inconvenience this causes to our fans or the festivals where we were scheduled to appear,” the band said. “As you must be, we too are disappointed at this unfortunate turn of events.”

Neil Young and Crazy Horse were set to play the Capitol Theater in Port Chester, NY, the Greenbelt Harvest Picnic in Dundas, Ontario, the Ottawa Folk Festival in Ottawa, Ontario, and the Interlocken Festival in Arrington, VA. They have been on tour for a year.

These cancellations aren’t looking good; earlier this year, Sampedro said that the tour might be their last. “I just think once it stops, it’s going to be kind of hard to get it rolling again,” Sampedro told Rolling Stone. “My gut tells me this is really the last tour. I hate saying their ages, but I’m 64 and I’m the baby of the band. I love playing, and we’re playing as good as we ever did, but at any time, something could go down with any one of us.”
