There was a rumor about him fighting Bob Sapp, a K1 fighter and ex-offensive lineman. He was the one in "The Longest Yard" that was lifting the bleachers with people on them for exercise. When asked if he would fight Tyson, he said that his teeth were just as good, but it never materialized. I don't think we'll see Tyson in any pro-sport again. He's too volatile and undisciplined.
