In August, Sapp participated in a special K-1 event in Las Vegas, where he went against Ultimate Fighting Championship veteran Kimo Leopoldo. Sapp had trained orthodox kickboxing with fellow UFC champion Maurice Smith for the match, and it could be noted in several powerful punches and knees that stunned Leopoldo. However, Sapp's stamina started to falter, which a slightly better conditioned Leopoldo capitalized on to take his turn, eventually knocking Sapp down at the end of the round. Controversy happened before the second, as referee Nobuaki Kakuda seemed to be deliberately giving Sapp time to recover, but the match continued anyways. Perceiving himself outclassed at a technical level, Sapp decided to return to his old bullrushing style, which paid off quickly by knocking Leopoldo down with a left hand. The UFC fighter tried to return the favor, but Sapp was already en route to overpower him and finally rendered him KO with an unchecked rabbit punch. In a marked contrast to Japan, American audiences booed Sapp.
