Dmitriy Bivol W12 Michael Eifert ... World light heavyweight champion Dmitriy Bivol made a successful return from back surgery on Saturday in Ekaterinberg, Russia. Bivol was never tested and showed no ill effects from the surgery while handily defeating lightly credentialed Michael Eifert of Germany. Bivol scored a first-round knockdown then cruised to a twelve-round decision victory by three scores of 120-107. Eifert showed heart but simply was levels below the future hall of famer. For thise keeping track of belts, Bivol owns three of the four major straps, with David Banvidez holding the WBC version, even though he has already moved up to cruiserweight. Next up for Bivol seems to be a third fight vs. former champion Artur Beterbiev.
