Press Release: Four days ahead of their IBF eliminator in Erfurt, Germany, Alexander Povetkin and Chris Byrd displayed their skills in public during Tuesday´s official press work-out. The former IBF and WBO champion was the first man in the ring. Instructed by father and coach Joe, Byrd (40-3-1) proved his mobility and speed. "I am in great shape," he vowed. "I've been through so many twelve-round fights in my career. My experience will help me."  Meanwhile, Povetkin (13-0) remained tight-lipped, suggesting he will let his fists do the talking in the ring. "My training has been geared towards a world title fight for over a year," he said. "I am determined to take the first step." The winner of Saturday's encounter will face the Calvin Brock-Eddie Chambers winner. European middleweight champion Sebastian Sylvester and his opponent Simone Rotolo also worked out in front of the boxing fans, as did Mads Larsen, Yoan Pablo Hernandez and Jimmy Kapanov.
