Rascal Flatts have had to cancel three more shows due to lead singer Gary LeVox' illness. The trio, who canceled their show in Oklahoma City last month, have also canceled their upcoming shows in Idaho, Washington and British Columbia, scheduled for Aug. 7, 8 and 9.

“It is incredibly difficult to make the decision to cancel shows and disappoint our loyal fans who have been so good to us over the years," band member Jay DeMarcus explains. "The schedule of shows this past weekend, coupled with media days in New York City, have left him without a voice. We promise to return as soon as we can and give our fans the best show possible!”

The threesome are crossing the country on their Rewind Tour, which kicked off in May and includes opening act Gloriana, and Sheryl Crow as their special guest. Fans can contact the venues where concerts were scheduled to be held for refund information.

The tour is scheduled to resume on Aug. 15 in Phoenix, Ariz. See a list of upcoming shows here.
