i dont know for sure,
but i think one fighter is selected from each weight class to represent their country.
if you can only compete in one division you can only get one medal.
time out!! 1904 you were allowed to compete in multiple weight classes as long as you werent overweight at the weigh in
oliver kirk, bantamweight and featherweight gold medals... USA BABY!!!
