Winston-Salem, NC-Grammy-winning folk musician Doc Watson remains in critical condition at a North Carolina hospital after undergoing colon surgery last week.
A spokeswoman at Baptist Hospital in Winston-Salem said Sunday that Watson was still in critical condition.
The 89-year-old Watson's daughter, Nancy, says that the musician fell a week ago.
The blind singer and guitarist has won several Grammys, including a lifetime achievement award. He also received the National Medal of the Arts.
Watson is known as a master of the flatpicking style of guitar playing. He also started Merlefest, an annual gathering of musicians in Wilkesboro named after his son, who died in a tractor accident in 1985.
