Accidental Injuries from Head Butts or other causes

If a fighter can not continue in a championship after sustaining a fight ending injury from caused by an accidental clash of heads or other causes, the outcome of the fight will be decided by a TKO loss for the fighter who can not continue.  


Competent scoring must be done using the following criteria:

When the fighter uses their fists, feet, knees, and elbows as effective and controlled MuayThai fighting weapons to attack their opponent powerfully, accurately, and according to the rules with effective and powerful techniques scoring higher than less effective strikes. The effective execution of any weapon will score higher than a less effective/timid execution of another weapon.

 Scoring Procedures

Fighters who can do more damage to their opponent using all MuayThai fighting weapons effectively, with heavier, powerful, and accurate attacks on their opponent, using clear, effective aggression with their offensive skills (damage), ring-craft skills (dominance), and defensive skills (disruption) by MuayThai arts and techniques, all contribute to a boxer winning the round – with extra credibility leaning towards the effective execution of attacking techniques.

The Ten Point Must System & Scoring Explained

The winner of a round must have 10 points

The loser of a round will get 9, 8, 7, or a low of 6, depending on various factors in the round.

If there is no clear winner, both fighters will get 10 points – if in doubt – score it even point deductions by a referee for fouls in a championship fight are cumulated on the supervisor’s master sheet

A 10-10 score shall be given when a judge’s mental computation at the end of the round is not clear enough to give a highly questionable round to either fighter.

Just because you have been instructed against scoring even rounds, it would be unfair to a fighter to score a round in favor of the other fighter if your mental computer witnessed no difference.

A 10-9 score shall be given in a round with a slight advantage in overall action favoring one fighter.

A 10-9  score shall be given, also, when there is a clear advantage but not an overwhelming advantage.

A 10-8 score shall be given when there is a knockdown, and the rest of the round is a very slight advantage for the fighter who scored the knockdown

A 10-8 score shall be given when there is an overwhelming one-sided round; even without a knockdown, a real beating by one of the fighters over the other shall be always a 10-8 round

A 10-9 score shall be given to fighter A when fighter B takes an eight-count, but B clearly and unquestionably wins the rest of the round, before and after the knockdown

A 10-10 score shall be given when a knocked down fighter gets up and then knocks down his rival with the rest of the round, somehow even

A 10-9 score should be given when both fighters are knocked down – but one of them wins the rest of the round

A 10-7 score shall be given on two knockdowns of the same fighter – but always consider what happened before and the knockdowns

No round should be scored lower than 10-6

Make sure that your scorecard is accurate and reflects your decision on each round before handing the card to the referee

At the start of each round, a judge will set his/her mental computer at the sound of the bell to 10-10, even or no advantage count

When a judge’s mind is immersed – without any distraction to compute even scoring – and sees no difference in the action of the fighters precisely at the end of the round – this is a 10-10 round

Your competent mental computing has one of the fighters slightly ahead of the other based on what you witnessed over the entire round. As we do not want many even rounds, a slight advantage should be a 10-9 round (Close)

 Your computing of the actions leads you to have one of the fighters ahead after completing the entire round. This is also a 10-9 round (Moderate)

Your computing of the actions leads you to have one of the fighters winning the round by a large margin of victory. This is also a 10-9 round (Decisive)

Your mental count sees one fighter give a one-sided beating and hurt their opponent throughout the round – the only thing missing was a knockdown. This is a 10- 8 round – don’t fear being right (Extreme Decisive)

Clean and effective strikes: Landing punches, elbows, knees, or kicks to the scoring area of your opponent with power, volume, and accuracy to cause damage, domination, or disruption to your opponent

Damage: If a fighter is trying to hurt their opponent, a judge should look for evidence of damage knocking your opponent down, staggering your opponent, significant blows that slow your opponent’s attacking prowess

Domination: If a fighter is trying to control their opponent, a judge should look for evidence of domination, an overwhelming advantage in strikes landed repeated initiates action during exchanges repeatedly lands the last strike in exchanges

Disruption: If a fighter is trying to prevent their opponent from hurting or controlling them, a judge should look for evidence of disruption, effective counter strikes that alter an opponent’s strategy that force an opponent to grab, and hold strikes that force an opponent into a defensive posture

Effective Aggression: A forceful willingness to attack your opponent (either moving forward, backward or remaining stationary) where your strikes land accurately and force on your opponent. Remember, there is a fundamental difference between effective aggression and aggression

Ring Generalship: Controlling the balance, pace, positioning, and style of the fight to a greater degree than that of your opponent

Defense: Displaying successful evasive maneuvers to avoid being hit and showcasing defensive mechanisms as part of an offensive strategy to attack your opponent and negate their attacks

Concentrate on your task over the entire fight

  • Treat each round separately
  • Never look back at the previous round · Do not look forward to the next round
  • Look for: Damage, Dominance, Disruption
  • Evaluate: Effective Aggression, Ring Generalship & Defense

When scoring knockdowns, one knockdown in a round is not automatically a 10-8 round, two knockdowns in a round in not automatically a 10-7 round, and three knockdowns in a round are not automatically a 10-6 round; a judge must also take into consideration what happened in action before and after the knockdown (s)

Clinch scoring

Scoring in the clinch

(i) MuayThai technique must land on target with power

(ii) MuayThai technique must be effective, or it is not scored

(iii) MuayThai technique must not have a foul or follow a foul
