Evander Holyfield

One of the more confusing aspects of boxing is the presence of three major organizations, each of which has a champion in 16 different weight classes (including the junior weight classes). These organizations are the World Boxing Association (WBA), the World Boxing Council (WBC), and the International Boxing Federation (IBF), and at any one time there may be a different champion in each organization. At other times, one man may hold the title in two of these, or the title might be vacant. To be undisputed champion in a weight class means that a fighter holds the title in all three organizations.
