John Wayne Bobbitt got cut off again ... and this time he suffered a broken neck.
JWB was driving to his brother's house in Buffalo Tuesday when another car ran a red light and T-boned his jeep. John suffered a broken vertebrae in his neck and a slipped disk.
We're told he should fully recover.
John notoriously beat his wife Lorena -- so she claimed -- and she got revenge in 1993 by cutting his penis off. Doctors reattached his schlong and John went on to do porn and screw scores of chicks.
We're assuming his penis is in fair condition.
