K-1 World Grand Prix 2001 Final was a kickboxing event promoted by the K-1. The event was held at the Tokyo Dome in Tokyo, Japan on Saturday, December 8, 2001, in front of 65,000 spectators. It was the ninth K-1 Grand Prix final, involving eight of the world's top fighters, with all bouts fought under K-1 Rules (100 kg/156-220 lbs). The eight finalists had almost all qualified by winning preliminary tournaments (with the exception of Peter Aerts who was a runner up), while two additional fighters were invited as reserve fighters in case of any injuries (for more detail on this see bulleted list below).
As well as tournament bouts there was also the aforementioned 'Reserve Fight' to decide who would be a replacement for any injured competition fighters, fought under K-1 Rules, and a 'Super Fight' between local middleweight star Masato and Noel Soares, fought under K-1 MAX Rules (70 kg/152 lbs). In total there were twelve fighters at the event, representing eleven countries.
Hoost defeated Leko by 3rd Round Unanimous Decision 3-0 (30-27, 30-27, 30-28) but had to retire due to injury - Stefan Leko would replace him in the Semi Finals as Reserve Fight winner Mike Bernardo was also injured.
