Willie Nelson, 83, was forced to cancel two scheduled performances over the last week due to an undisclosed illness.

Willie, who has toured perpetually over the course of his Hall of Fame career, cancelled shows in Midland, Texas, on Nov. 13 and in Lubbock, Texas, on Nov. 15. Willie’s next performance is slated for Nov. 18 in Lake Charles, La., and he still has more than a handful of dates on the schedule before the end of the year.

In September, Willie released his latest album, For the Good Times: A Tribute to Ray Price. More recently, following the 50th annual CMA awards on Nov. 2, Willie stopped by Jimmy Kimmel Live to spend some quality time with the late-night talk show host and enjoy a cocktail while playing Three Ridiculous Questions.

Here’s hoping Willie gets well soon.
