During the past 11 months, undefeated and reigning North American Boxing Federation and United States Boxing Association heavyweight champion Samuel Peter of Las Vegas has made considerable headway in his assault on a world title. “My life’s mission is to get a belt and be recognized as world champion.” said Peter.  “I was meant to be heavyweight world champion and I won’t stop until I am. I will be heavyweight world champion.  (World Boxing Council heavyweight champion Vitali) Klitschko, (World Boxing Association heavyweight champion John) Ruiz, (International Boxing Federation heavyweight champion Chris) Byrd and (World Boxing Organization heavyweight champion Lamon) Brewster have something I want," said Peter.
