On 24 September 2005 he faced Wladimir Klitschko in an elimination match in Atlantic City for the IBF title, in which Peter's WBC-NABF title was also on the line. Coming into the bout, Klitschko was viewed by many as the underdog against the 7-to-5 favorite Peter who had won all of his 24 fights, with 21 of them having ended inside the distance. At the time, Samuel Peter was considered one of the brightest prospects in the heavyweight division. Distinguished boxing coaches Angelo Dundee and Teddy Atlas expected Peter to win. Wladimir's team, including his brother Vitali, were worried about Wladimir, and were against this fight to happen. Wladimir, however, insisted on fighting Peter, claiming that beating a feared, hard-hitting fighter like Samuel Peter would help him to regain his stock and become mandatory challenger for two heavyweight belts.
