What happens if a foul ends an MMA fight?

A foul can decide a fight. An intentional foul that ends the bout means disqualification. An accidental foul that ends it gives a no contest if fewer than half the scheduled rounds are complete, and a technical decision on the scorecards after that. A technical draw is possible when a fighter fouled earlier is level or behind.

How it works

  • Intentional foul, fight ended at once: the fouler loses by disqualification.
  • Disqualification also follows: multiple fouls, or flagrant disregard of the rules or the referee's commands.
  • Accidental foul, stopped before half the scheduled rounds: a no contest. The text also allows disqualification.
  • Accidental foul, stopped after half the scheduled rounds: a technical decision for whoever is ahead on the cards.
  • Part rounds: scored. A round with no action is scored even.
  • Intentional foul, fight goes on, then the same injury stops it after half the rounds: the injured fighter wins a technical decision if ahead, and the bout is a technical draw if they are level or behind.
  • Loss of bodily function during a round: a technical knockout by medical stoppage against that fighter.

The glossary has the disqualification, the no contest, the technical decision, the technical draw, the intentional foul and the accidental foul.

Tricky cases

An accidental eye poke ends a three-round fight in the first round. What is the result?

A no contest. The foul was accidental and fewer than half the scheduled rounds were complete.

The same poke ends the fight in the third round. What is the result?

A technical decision. The cards are added up, including the partial round, and the fighter ahead wins.

A fighter throws an illegal knee on purpose and the opponent cannot continue. What is the result?

Disqualification of the fighter who threw it.

Who decides whether a foul was intentional?

The referee. The rules give no test for it, and the whole result can turn on that judgement.

Why the rule exists

A fighter who cannot continue because of an illegal blow should not lose by it, and a fighter who fouled by accident should not be thrown out as if it were deliberate. The halfway line is a practical test of whether enough of the fight has happened for the scorecards to mean something.
