In a statement Friday, Adele said she was "really frustrated" but "there is absolutely nothing I can do but take the doctor's advice and rest some more."
The announcement comes days after the singer postponed five dates on the tour. She is now canceling the nine remaining shows.
It's unclear at this point whether this, or any of the other affected shows on the North American tour, will be rescheduled. If you're in possession of tickets to this show, here's what The Ryman's website says: "Please hold onto your tickets until an announcement about rescheduling can be made. More information will be available via our Twitter and Facebook page as it becomes available."
