4. Luis Resto loads his gloves for his fight against Billy Collins Jr.
Punishment: Boxing license suspended for one year, convicted of assault and sentenced to 2.5 years in prison
Resto wasn't considered a big name outside the state of New York, and headed into his fight with the up-and-coming Collins he was viewed largely as a stepping stone for his promising opponent. Resto, however, shocked experts when he took a 10 round unanimous decision over the visibly pummeled Collins. However, a quick investigation revealed that an ounce of padding had been removed from each glove, rendering the blows of the light-hitting Resto significantly more effective. Collins' eyes were damaged to the extent that they ended his career, and months later he was dead after a car wreck.
