Country duo Thompson Square have cancelled a string of shows to allow singer Keifer Thompson time to battle a "very serious vocal condition".
Doctors advised the star to rest his voice weeks ago, but he refused and now his vocal issues have taken their toll on his ability to perform with bandmate and wife Shawna Thompson.
The pair has axed its U.S. gigs until Sunday (02Jun13) in the hope that a break will give Thompson time to recover.
A statement from the singer on the band's website reads, "It breaks my heart to tell our fans today that we must cancel our upcoming concert appearances this weekend. What many of you may not know is that I have recently been battling a very serious vocal condition.
"I was urged by doctors to cancel Thompson Square's appearances and go on complete vocal rest several weeks ago; however, neither Shawna nor I wanted to disappoint our fans, which we love and respect dearly. So we chose to continue performing our scheduled shows while I remained completely silent offstage in an effort to heal.
"Unfortunately, at this time, I have been ordered by doctors to take the next step and to cancel this weekend's shows in an effort to heal internally.
"Words cannot express how devastated we both are to bring this news to our fans. We hope that you will understand what a difficult decision this has been and know that we can't wait to get back out on the road and make it up to you as soon as possible."
