- A man taking excessive knees to avoid further abuse may be disqualified at the discretion of the referee.
- A man hanging on the ropes in a helpless state, with his toes off the ground, shall be considered down thus ending the round.
- No seconds or any other person to be allowed in the ring during the rounds.
- Should the contest be stopped by any unavoidable interference, the referee to name the time and place as soon as possible for finishing the contest; so that the match must be won and lost, unless the backers of both men agree to draw the stakes.
- A man on one knee is considered down and if struck is entitled to the stakes by way of his foe's disqualification.
