Zac Brown has tested positive for COVID-19.

The 43-year-old singer revealed on Instagram that Zac Brown Band would have to put their “Comeback Tour” on pause while he recovers from the virus.

“I have made the very difficult decision to pause Zac Brown Band’s ‘The Comeback Tour,’” the frontman wrote. “Despite taking precautions, I’ve tested positive for COVID-19. I am deeply disappointed this has happened, as touring is our life and performing live for our fans is the best part of our job.”

He added the number one priority is their safety, writing: “The bottom line is that I want to take every precaution to put the health and safety of our fans and crew first. We will resume the tour as soon as I have finished the CDC-mandated quarantine and it is safe for our band members and crew to do so.”

The singer did not reveal whether he or any of the band members or crew had been vaccinated, or if any additional members had tested positive.
