HOFFMAN ESTATES, Ill. -- Two Russian fighters, heavyweight champions both, rose Saturday morning on different contents intent on defending titles in their respective sports. For boxing's lumbering giant Nikolay Valuev the call was not answered, as he surrendered the WBA belt on points to Brit David Haye. The fate of his mixed martial arts counterpart, the revered Fedor Emelianenko, will be known shortly as he steps into the cage for the first time in his career.
