Felix Sturm
In his last fight of 2006, Dimitrenko faced an experienced American journeyman Billy Zumbrun on 18 November 2006, only three weeks after beating Basile. Originally, the main event of the card was supposed to be the fight between Felix Sturm and Gavin Topp, but the fight was postponed due to Sturm's injury. Dimitrenko, regarded as a popular commodity in Germany at the time, was considered to be an adequate replacement for Sturm. According to Dimitrenko, the fight turned out to be "tougher than expected".
