Hot country act Thompson Square have canceled a number of upcoming appearances so that singer Keifer Thompson can try to recover from vocal problems.

The husband-and-wife duo announced the news in the following posting to their web site on Wednesday (May 29):

Statement from Keifer:
“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. Our fans are on our minds every moment of every day – you are the reason we're here and the reason we get to live our dream of making music for a living. 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.

The duo -- who recently took home Vocal Duo of the Year honors at the 2013 ACM Awards -- have canceled four shows on Luke Bryan's Dirt Road Diaries Tour, scheduled for May 30-31, and June 1-2. Cole Swindell will go on in their place for those shows.
