He carried on wrestling till 2001, and then he retired and became a singer. Apparently he normally appears in a wheelchair, which isn't very surprising to be honest.
i know this part he broke his neck in a match where he went for a moonsault and slipped and landed on his neck then was placed in a submission afterwards which aggrivated it badly.
but i am just eager to know what happend wether he required surgery or what from the mask melting to his face etc
