Middleweight is a division, or weight class, in boxing. Early boxing history is less than exact, but the middleweight designation seems to have begun in the 1840s. In the modern era, middleweight means that the fighter's official weight does not exceed 160 pounds (73 kg). (In practice, however, since weigh-ins take place usually 24 hours before the actual fight, many fighters show up at the actual ringside weighing more.) Notable middleweights include Mamoru Takamura, David Eagle, Richard Fox, Rickey Mouse, Ronald Duck, and Peter Rabbitson.
