Sergei Kharitonov (Pictures) has agreed to fight American knockout artist "Mighty Mo" Siala Siliga (Pictures) at K-1 PREMIUM Dynamite!! on New Year's Eve, the Russian heavyweight confirmed the bout on his Web site.
The 27-year-old Muscovite is a former No. 1 challenger for the PRIDE heavyweight title and holds wins over two-time K-1 World Grand Prix Final champion Semmy Schilt (Pictures), three-time Brazilian jiu-jitsu world champion Fabricio Werdum (Pictures) and current Strikeforce heavyweight champion Alistair Overeem (Pictures).
Kharitonov, a practitioner of Combat Sambo as well as a former Russian amateur boxing champion, had been with Russian Top Team for more than seven years before he joined the ranks of Dutch squad Golden Glory in September.
Siliga, 10 years older than the Russian, started out as a journeyman boxer, but quickly became one of the K-1's major stars when he entered the ring in 2004. The two biggest achievements of the heavy-handed Samoan are his wins of the 2004 K-1 World Grand Prix in Las Vegas and this year's K-1 World Grand Prix in Hawaii.
The 6-foot-1, 300-pound slugger is best known for his unbelievable knockout of Korean 7-foot-2 "Techno Goliath" Hong-Man Choi, whom he knocked out cold with a powerful overhand right at the two fighters meeting in April.
Starting this year, K-1 promoter FEG started pushing him in their MMA division HERO'S as well. In March he knocked out Olympic judo silver medalist Min Soo Kim (Pictures) and followed up with another KO win over heavyweight jobber Ruben Villareal (Pictures) at K-1's Dynamite!! USA show in June.
Kharitonov, a veteran of almost 20 mixed martial arts fights, enters the MMA fight against Siliga (3-0) as the much more experienced fighter and heavy favorite.
Previously announced for the Dec. 31 show was a middleweight encounter between Japanese legends Kazushi Sakuraba (Pictures) and Masakatsu Funaki (Pictures) as well as a lightweight kickboxing bout between former K-1 World MAX champion Masato and former WBA super featherweight champion Yong Soo Choi.
The promotion has also openly thought about matching current K-1 World MAX champion Andy Souwer (Pictures) with Japanese 132-pound kickboxing prodigy Hiroya in another lightweight kickboxing duel.
