juddpic230crop.jpgCactus Moser, Wynonna Judd's husband, had his left leg amputated above the knee following a motorcycle accident over the weekend.

Judd's rep said that Moser's leg was "severed at the scene of the accident."

The drummer, who married Judd in June, drifted across the center line of a road in Deadwood, S.D. ... and crashed into an oncoming car.

Wynonna released the following statement following the accident:

"Cactus is a champion. I love him deeply, and I will not leave his side."

Moser also needed surgery on his hand.

Wynonna has postponed concerts in Canada next week to be with her husband.
