Rascal Flatts just canceled their show tonight in San Diego, California.

According to a post on their Twitter account, they’ve been forced to cancel the show after an unspecified illness.

Fans who purchased tickets to the show will receive a refund.

At this time, the nature of the illness is not known, nor is it known which band member fell ill.

Prior to the cancellation, the country group was scheduled to perform at the Mattress Firm Amphitheatre.

Dan + Shay were slated to open for Rascal Flatts.

After learning of the cancellation, Dan + Shay also issued a tweet saying that while the scheduled show will not go on, the duo will perform for fans at another location.

The surprise pop up show will take place at the House of Blues.

We hope the band member who fell ill makes a speedy recovery.

Rascal Flatts has another show scheduled in Irvine, California tomorrow.

It is not yet known if that show will go on as planned or not.
