Glaube Feitosa
Hug went 4–0 in 2000, the year of his death. He took a majority decision in his rematch with Musashi at "K-1 Burning 2000" on March 19 and a unanimous decision against Glaube Feitosa after a back-and-forth war at "K-1 The Millennium" on April 23. In his Swiss retirement fight (his last fight in Switzerland) as well as his fourth and last WKA title defence, Hug defeated Mirko Cro Cop at "K-1 Fight Night 2000" on June 3. Cro Cop put him under pressure with his boxing at numerous times, but Hug stayed active with his kicks and did enough to take the unanimous decision.
