Wynonna Judd's husband and drummer Michael Scott "Cactus" Moser's left leg was amputated above the knee following a motorcycle accident on Saturday in South Dakota.

The leg was severed at the scene and doctors in Rapid City performed the surgery.

He also underwent surgery to his hand.

In a statement posted at Wynonna.com, the couple expresses their appreciation for "all of the quick medical and police responders as well as the hospital staff and well-wishes from family, friends and fans."

Judd has canceled her concerts for the next week as a result of the accident. Her next scheduled date is set for August 30 in Michigan.
