I heard he was wrastlin a match back in the day againts Mr. Perfect and his leg actually fell off...he rolled outside the ring and under the ring and was gone for a little while....I guess he was under there re-attaching it.
The Von Ericks have a very "wierd" history...lots of them are dead or died under wierd circumstances, kerry commited suicide.
and here's confirmation:
On June 4, 1986, Kerry was in a motorcycle accident that nearly ended his life and left him with a dislocated hip and a badly injured right leg. Doctors eventually had to amputate his right foot. (According to brother Kevin, Kerry injured the foot following surgery by attempting to walk on it prematurely, crushing the bones beyond repair and thus forcing the doctors to amputate it.) He was able to continue wrestling after the accident with a fused ankle.
Kerry was able to keep his amputation secret for a while. However, during a match on an AWA card in Las Vegas against Colonel DeBeers, Kerry's secret was exposed. During the bout, DeBeers ended up on the outside, but he grabbed Kerry's foot and tried to pull him out of the ring. However, he ended up pulling off Kerry's boot with the prosthetic foot attached.
A lot of wrestlers said after his foot was amputated(they didn;t know either) Kerry would shower with his boots on....
