 Rounds were not timed but instead lasted until a man was knocked down, with fighters permitted to wrestle each other to the ground.Moving around the ring, known as shifting, was deprecated and sometimes explicitly prohibited by the rules for a fight; going to ground without being hit could lead to claims that the man still standing had won.The fighters usually each provided an umpire of their choice, and there might also be a third, independent umpire present, to adjudicate between them.
