Daniel Jacobs and Gennadiy Golovkin both knocked down Sergiy Derevyanchenko in the first round.
Neither Jacobs nor Golovkin could keep the determined Derevyanchenko down, though. The Ukrainian middleweight contender got up from both of those knockdowns to give Golovkin and Jacobs very difficult fights Derevyanchenko ultimately lost on points.
Jermall Charlo thus understands that knocking out Derevyanchenko in their 12-round, 160-pound championship match September 26 would lend credibility to his WBC middleweight championship reign.
