Guitar legend Leslie West is in stable condition after having his lower right leg amputated. The Mountain legend and heavy metal pioneer is a diabetic and underwent emergency surgery after severe swelling, according to Spinner.com.

His wife Jenni explained in a press statement that: “The doctors tried for two days to save it to no avail. The decision to amputate was one that was necessary to save his life as the infection was spreading throughout his body.”

West is expected to make a complete recovery but his family ask that the “the public and media respect his privacy while he comes to terms with this life-changing transition.”

West has been working on a new Mountain album, The Unusual Suspects, featuring collaborations with Slash, Billy Gibbons, Zakk Wylde and Joe Bonamassa.
