Loretta Lynn has been forced to postpone two additional concerts following a surgery she underwent after a fall in late August.

According to a Facebook post from Gruene Hall in New Braunfels, Texas, Lynn's two sold-out concerts at the venue scheduled for Friday (Sept. 23) and Saturday (Sept. 24) are being postponed. Organizers write that they are "currently working to find a replacement date," but in the meantime, tickets will be refunded through the original point of purchase.

Lynn’s fans first learned of her fall over Labor Day Weekend. When concertgoers showed up for her Labor Day show, which takes place each year at Lynn’s Hurricane Mills, Tenn., ranch, they were informed that the 84-year-old singer had fallen and injured herself earlier that week and would not be performing. Lynn’s sister, Crystal Gayle, read a note to fans from Lynn that explained “I injured my chest and can’t get a deep enough breath to sing.” On Sept. 7, it was revealed that the country icon required "minor surgery" as a result of the fall; though her injuries were not serious, Lynn's doctors advised her to stay off the road until she's fully healed.

Prior to the cancellation of this weekend's Texas shows, Lynn canceled appearances in Renfro Valley, Ky., on Sept. 9; in Newell, W.V., on Sept. 10; and in Bristol, Tenn., on Sept. 17, as well as an appearance at the Grand Ole Opry on Sept. 16. The next date on her tour calendar is Oct. 8 in North Myrtle Beach, S.C.

Lynn is on the road promoting her newest album, Full Circle. The project earned Lynn her highest-ever chart debut on the all-genre Billboard 200 following its release on March 4. The record is available via Amazon and iTunes.
