Marciano is the only heavyweight champion to retire with an undefeated record, though he is often omitted from the lists of the greatest of all time due to the realitivly low level of competition in the heavyweight division at that time...
yes he is still a boxer but he is not a heavyweight boxer.
He was undefeated in six bouts, although the talent level of his heavyweight opponents was negligible. He returned to the Dallas Cowboys for the 1980 season.
Humberto Soto - heavyweight boxer - was born on 1980-01-21.
A boxer must weigh at least 200 pounds to be considered a heavyweight.
To become a heavyweight boxer, you will have to put in a lot of work and training. You will have to spend a lot of time at the gym with a trainer. Eat healthy, while still maintaining the proper weight for a heavyweight.
Rocky Marciano
The probability is zero since the rules governing boxing would not permit a heavyweight boxer to fight at flyweight.
Uh, yes.
Leon Spinks
Roy Jones Jr is the only boxer who has ever captured titles in middleweight, super middleweight, light heavyweight and heavyweight divisions. He began his career at 154 pounds but by the time he had won his heavyweight champions he weighed 193 pounds.
