Nickelback's "No Fixed Address" world tour has been scrubbed entirely.
Representatives for the Alberta rockers say all remaining tour dates have been cancelled due to an extended period of vocal rest ordered for lead singer Chad Kroeger.
Nickelback cancelled the second leg of the tour in June when doctors first diagnosed Kroeger with a cyst on his vocal cords.
He recently underwent surgery and the group was scheduled to resume the European leg of the tour in September.
But doctors now say Kroeger needs to remain on vocal rest for the next six to eight months in order to heal completely.
Organizers say ticket refunds will be available at the point of purchase.
"Most of all, we are sorry to miss our fans out on the road this fall, but Chad's health, healing and full recovery are what is most important right now," the group said in a statement.
"With the proper amount of time, we hope to have him back stronger and better than ever before. We thank everyone for their support and understanding during this time and look forward to getting back out on the road and playing music for everyone again real soon."
