Former world heavyweight champion Samuel Peter says he’s ready to rumble for the world title. “Doesn’t matter who — either of the Klitschko’s for starters,” said Peter, the ‘Nigerian Nightmare’ who now lives and trains in Las Vegas. He has won three straight fights while boxing for Top Rank. Peter, 29, has a record of 33-3-0. He is ranked WBC #10. On Saturday, Peter stopped 363-pound Gabe Brown, knocking him down and stopping him in four rounds, on the Kelly Pavlik-Miguel Espino title card in Youngstown, Ohio. “Peter is a former world champion. He’s been at the top. He hits hard and he’s ready for a crack for the title,” said Bruce Trampler, chief matchmaker for Top Rank.
