5. Igor Vovchanchyn (Pictures) vs. Fred Floyd -- March 30, 1996
Weight difference: 133 pounds
When Vovchanchyn met Floyd at the inaugural IFC show in Kiev, Ukraine, the stocky local hero had already earned a reputation as one of the most dangerous strikers in the sport’s young history. Despite knocking out nine of his previous 10 opponents, however, the man who would later become known as “Ice Cold” had never faced a specimen like the 6-foot-4, 340-pound American.
Floyd, a kickboxer from California, came in with an even record and brought the fight to his much lighter opponent from the opening bell. Things soon changed, though, as Vovchanchyn’s superior striking came into play and prompted Floyd to take the fight to the mat. After getting mounted, Vovchanchyn turned the tables and poured it on while he stood toe-to-toe with “The Mangler.”
Following 13 minutes of Vovchanchyn’s vicious haymakers, Floyd tapped out due to punishment and exhaustion.
