Little Big Town has had to postpone or cancel a handful of shows on their Pain Killer Tour as band member Jimi Westbrook is having to undergo vocal cord surgery. The band took to their website to let fans know Jimi is having a polyp removed from his vocal cords and part of his recovery includes resting his voice and not singing or talking.

“It breaks our hearts to let you guys down, but Jimi’s health is the most important thing, and he is expected to make a full recovery with rest and treatment,” the band writes. “We will keep everyone updated on Jimi’s progress. Thanks for your understanding and support.”

The band just finished hosting and performing at different events during this year’s CMA Music Fest. Currently, 13 shows through the end of July will need to be canceled or rescheduled.

The band is currently making its way up the country charts with their latest single, “Girl Crush.”
