Judd said she would reschedule concerts in Winnipeg, Manitoba (Aug. 21); Regina, Saskatchewan (Aug. 22); Carlylye, Saskatchewan (Aug. 24); and Llyodminster, Saskatchewan (Aug. 25.)
Her next concert after that is Aug. 30 in Peshawbestow, Mich., about 20 miles north of Traverse City.
Judd and Moser, 55, of Nashville, were riding motorcycles on state Highway 16 in the isolated Black Hills mountain range Saturday when he crossed the center line and hit the driver's side door of a southbound Chevrolet Malibu driven by Michael Bruce, 59, of Rapid City, the South Dakota Highway Patrol said.
Moser was airlifted to Rapid City Regional Hospital, the Rapid City Journal reported.
Moser's left leg was amputated above the knee, the Los Angeles Times reported. A representative for Judd said in a statement Monday Moser's leg was "severed at the scene of the accident."
Bruce declined medical treatment at the scene, police said.
Judd was riding ahead of her husband and was not involved in the crash. She canceled a show at the Deadwood Mountain Grand Hotel & Casino in Deadwood, S.D., scheduled for that night.
Moser, a drummer for Judd's band who previous played with country music band Highway 101, was cited for driving on the wrong side of the road and not having a license to operate a motorcycle, Berkley said.
Judd and Moser were married June 10 at her home in Leiper's Fork, Tenn.
A message on Judd's Facebook page said Judd and Moser were "both incredibly appreciative for the prayers and love. Wy fans are truly the best."
