Loretta Lynn is rescheduling eight upcoming tour stops to recover from reconstructive knee surgery. Earlier today, the singer announced on her website that her doctor had ordered her to rest the knee through September 2. "As of right now her Ranch date is still slated for September 3," the press release says.

“I’m sad to have to cancel any shows for my fans, but they tell me I’ve just got to stay off this knee for a while,” Lynn says on the website. The legend's health has prevented her from honoring concert commitments on more than one occasion in recent years, most notably in 2006 when she underwent shoulder surgery. She also was sidelined in July due to heat exhaustion and dehydration, and in April due to knee surgery. It's not clear if the work is being done on the same knee.

“Every time I get sick people start asking am I gonna stop doing shows," Lynn said backstage at the Grand Ole Opry last month, "but as long as I can sing and people wanna come see me, I’m just gonna keep on going!” All eight postponed shows were in the Northwest, with the exception of one date in Montana and one in South Dakota. Fan are encouraged to use their tickets for the rescheduled dates, but refunds are available at the point of purchase.
