By Ken Hissner: Amateur defeats have been reversed many times, and the one that comes to mind immediately is when Henry Tillman twice defeated Mike Tyson in the 1984 box-off by split decision and first in the trials by decision. In 1990 Tyson knocked Tillman, 20-4, out in the first round in Las Vegas, NV.
