Lady A's Request Line Tour, originally scheduled to begin on Aug. 13, is being postponed to 2023.
The band said it was postponing the tour due to band member Charles Kelley's "journey to sobriety."
"Being on the road with our fans is our greatest joy, so it was a hard but important decision to make," the country trio said in a statement posted to their social channels on Thursday.
