The six outcomes

Every sanctioned MMA bout ends in exactly one of six ways. The Unified Rules of MMA recognize:

  1. Knockout (KO)
  2. Technical Knockout (TKO)
  3. Submission
  4. Decision (unanimous, majority, or split)
  5. Disqualification (DQ)
  6. No Contest (NC)

Knockout (KO)

A KO is recorded when a fighter is rendered unconscious or unable to intelligently defend themselves due to strikes. The referee waves off the bout immediately, and the medical team enters the cage.

Sub-categories:

  • Straight KO — single strike or combination ends the bout cleanly. Examples: Holly Holm's head kick of Ronda Rousey (UFC 193), Conor McGregor's left hand of Jose Aldo (UFC 194).
  • Walk-off KO — the winning fighter walks away before the opponent has hit the canvas. Examples: Holloway-Gaethje at UFC 300, Edwards-Usman 2 at UFC 278.
  • Flash KO — single-strike finish where the recipient is unconscious only briefly before regaining awareness.

Total time unconscious during a KO is variable but typically 5-30 seconds for clean finishes. Modern medical protocols require a ringside neurological exam after every KO.

Technical Knockout (TKO)

A TKO is recorded when:

  • Referee stops the fight due to strikes: most common TKO type. The referee judges that the fighter can no longer intelligently defend themselves.
  • Corner stoppage: the fighter's corner throws in the towel. Famous examples: Aljamain Sterling's corner saving him during the Petr Yan rematch (though it wasn't formally a corner stoppage); the AKA corner saving Cain Velasquez against Fabricio Werdum at UFC 188.
  • Doctor stoppage: ringside physician halts the fight due to injury or inability to continue. Examples: Jorge Masvidal vs Nate Diaz at UFC 244 ended in a doctor stoppage after Masvidal's strikes opened cuts on Diaz's face.
  • Injury TKO: legal strikes cause a fighter to be unable to continue. Anderson Silva vs Chris Weidman 2 (UFC 168) ended with Silva's tibia and fibula breaking against a Weidman check kick.

The distinction between KO and TKO is the consciousness state — KO requires unconsciousness; TKO requires "unable to defend." Some strict commissions reclassify TKOs as KOs after the fact if the recipient was visibly unconscious.

Submission

A submission is recorded when:

  • Physical tap: the submitting fighter taps the mat, the opponent, or themselves visibly.
  • Verbal tap: the submitting fighter says "tap" or makes any submissive vocalization.
  • Visual tap: the submitting fighter visibly cries out or expresses pain (rare; most commissions require a physical or verbal tap).
  • Technical submission: the fighter is rendered unconscious by a choke without tapping. Examples: Fabricio Werdum's triangle-armbar of Fedor Emelianenko (Strikeforce, June 2010) ended with Fedor still trying to fight out.

Submission types are catalogued separately — chokes, joint locks, leg locks, neck cranks. See the Glossary for individual technique definitions.

Decision

A decision is recorded when the bout reaches the end of regulation rounds without a stoppage and judges' scorecards determine the winner. See 10-Point Must Scoring and Judging Criteria for how decisions are scored.

Decision types:

  • Unanimous decision: all three judges score for the same fighter.
  • Majority decision: two judges score for one fighter, the third scores it a draw.
  • Split decision: two judges score for one fighter, one for the other.

Draw types:

  • Unanimous draw: all three judges score it a draw.
  • Majority draw: two judges score it a draw, the third for one fighter.
  • Split draw: each fighter wins one card, the third is a draw.

Disqualification (DQ)

A DQ is recorded when one fighter commits an intentional foul that incapacitates the opponent and prevents continuation. The fouled fighter is declared the winner.

DQs are rare in modern UFC history. The most famous:

  • Matt Hamill defeats Jon Jones (UFC: The Ultimate Fighter 10 Finale, December 2009): Jones disqualified for repeated 12-to-6 elbows while in mount. Now legal under 2024 rules; at the time, the only loss on Jones's career record.
  • Petr Yan vs Aljamain Sterling (UFC 259, March 2021): Yan disqualified for an illegal knee to a grounded Sterling. Sterling won the bantamweight title by DQ — the most consequential DQ in modern title-fight history.
  • Falaniko Vitale defeats Matt Lindland (UFC 43, 2003): Lindland disqualified for repeated headbutts.

No Contest (NC)

A No Contest is recorded when:

  • Accidental foul causes injury that prevents continuation, and the bout hasn't reached the point where a technical decision could be rendered. Examples: many eye-poke-induced stoppages.
  • Drug test failure after the bout is overturned to NC. Examples: Jon Jones vs Daniel Cormier 2 (UFC 214) was overturned to NC after Jones tested positive for turinabol; Anderson Silva vs Nick Diaz (UFC 183) overturned after both tested positive (Silva for steroids, Diaz for marijuana).
  • Mutual disqualification or other irregularity.

NCs do not count as wins or losses on either fighter's record.

Technical decision (rare)

A technical decision can occur when:

  • An accidental foul causes injury that prevents continuation after the bout has reached three completed rounds in a three-round bout, or three completed rounds in a five-round bout. The judges' scorecards through the completed rounds determine the winner.
  • A fighter is unable to continue due to a non-foul injury after the bout has crossed the round threshold above.

Technical decisions are statistically rare but provide a path to a sanctioned outcome when the bout cannot finish cleanly.

Statistical breakdown

Across UFC bouts 2015-2024, the approximate distribution of finishes:

  • Decisions: ~52% of bouts (unanimous ~38%, split ~10%, majority ~4%)
  • TKO: ~25%
  • KO: ~12%
  • Submission: ~10%
  • DQ / NC: ~1% combined

The high decision rate reflects the modern matchmaking culture where evenly-matched competitive bouts are prioritized over mismatches. Earlier UFC eras (1993-2005) had significantly higher finish rates because the bracket included one-sided matchups intentionally.

Performance bonuses (UFC-specific)

The UFC distributes four $50,000 bonuses per card:

  • Fight of the Night (one bout, both fighters receive)
  • Performance of the Night (two awards for individual standout finishes)

The bonus structure incentivizes finishes — fighters who pursue a finish at the risk of losing are more likely to receive bonus payments than fighters who play it safe for a decision win.
