Shania Twain has been forced to cancel two of her 2015 Rock This Country Tour dates due to doctor's orders.

The singer has been diagnosed with a respiratory infection, and doctors have advised her to rest for several days, according to a post on Twain's Facebook page. Twain's Oct. 6 show at the Verizon Wireless Arena in Manchester, N.H., and her Oct. 7 concert at the Times Union Center in Albany, N.Y., are the two dates affected.

Unfortunately, due to her current touring schedule, these two dates will not be rescheduled, the Facebook post continues. Tickets will be refunded at their point of purchase.

"Shania Twain apologizes for any inconvenience this may cause her fans," the post says, "and greatly appreciates their understanding."

Twain began her Rock This Country Tour in June, in Seattle, Wash. There are only two dates remaining on the trek at this time: Oct. 9 at the Videotron Centre in Quebec City, Quebec, Canada, and Oct. 11 at the Air Canada Centre in Toronto, Ontario, Canada.

This tour is Twain’s first North American tour in more than 11 years. Unfortunately, the singer announced earlier that this tour will be her last.

“I just feel like I’m ready to hang my hat up in that regard,” she says. “I just really want to go out with a bang.”

More information on Twain's remaining 2015 Rock This Country Tour dates can be found on Twain’s website.
