Amateur: 3; also five-two min rounds. Pro: 4; 6; 8; 10; 12 no laws against "15" round matches still. Are their 'laws' against 20 r. boxing?? If their are/ those laws are most certainly -regional- and no possible further jurisdiction. Now: are "5" r. boxing matches ever slated? The answer is yes and you WILL SEE them in records if you keep searching long enough. I have seen them many times. Are their ever two round matches slated? again, they do exist in records. Even one round slatted distances are to be found in records. "7" round matches have happened. As have "11" r. matches. Normally it is even number rounds that are used. (note: their are many, many boxing matches happening around the Globe, every month and the numbers would -probably- amaze the average joe on street).

4595
