Wynonna Judd's Husband Has Leg Amputated After Motorcycle Crash

Judd's rep tells us ... Michael Scott Moser "severed" his leg in the crash ... and when he was transported to a hospital in Rapid City, SD doctors determined it was necessary to amputate the leg above the knee.

The rep also says Moser had to undergo surgery on his hand, which is of particular concern because he is the drummer in Judd's band.
