In 1988 Rick Roufus challenged Changpuek Kiatsongrit to a non-title Muay Thai vs. kickboxing super fight. Rick Roufus was at the time an undefeated Kickboxer and held both the KICK Super Middleweight World title and the PKC Middleweight title. Changpuek Kiatsongrit was finding it increasingly difficult to get fights in Thailand as his weight (70 kg) was not typical for Thailand, where competitive bouts at tend to be at the lower weights. Roufus knocked Changpuek down twice with punches in the first round, breaking Changpuek's jaw, but lost by technical knockout in the fourth round due to the culmination of low kicks to the legs that he was unprepared for. This match was the first popular fight which showcased the power of such low kicks to a predominantly Western audience.
