Heavyweight boxing world champion Wladimir Klitschko of Ukraine weighed 112KG [246.9-pounds], and his challenger Samuel Peter weighed 109.5KG [241.4-pounds], at the official weigh-in in Frankfurt, central Germany. Heavyweight champion Wladimir Klitschko is predicting a quick knockout in his rematch with Nigerian fighter Samuel Peter on Saturday. Klitschko says he is a much better fighter than he was five years ago when he was sent to the canvas three times before beating Peter in an unanimous decision. Peter is challenging the Ukrainian holder of the IBF, WBO and IBO heavyweight belts and is equally confident of a quick victory.
