TKO vs KO in Boxing: Methods of Victory Explained

A boxing match can end in more ways than most fans realise. A single punch, a corner throwing in the towel, three judges disagreeing on a scorecard, an accidental clash of heads. Each one has its own name and its own consequences, both for the boxer’s record and for how a Method of Victory bet is settled.

The two most famous stoppages are the Knockout and the Technical Knockout, and the difference between them matters more than most people realise. This guide explains what a KO is, what a TKO is, how the two compare on the record, and how every other method of victory works in professional boxing, from decisions and retirements to disqualifications and draws. For the odds on the next big fight, head over to boxing betting at BetVictor.

What Is a Knockout (KO) in Boxing?

A Knockout is declared when a fighter is knocked to the canvas by a legal strike and cannot rise to their feet before the referee counts to ten. The referee starts the count from the moment the fighter hits the canvas and continues at one-second intervals. If the fighter is not back on their feet and demonstrating awareness by the count of ten, the fight is over.

The KO is boxing at its purest. There is no intervention from the corner, no ringside doctor, and no judge required to declare the winner. The fighter is either up and defending themselves before the count reaches ten, or the fight is over.

How the 10-Count Works

When a fighter goes down, the referee sends the standing fighter to a neutral corner and then begins the count. Even if the downed fighter beats the count at nine, the referee has the discretion to stop the fight if they judge that the fighter is not fit to continue. When that happens, the result is recorded as a Technical Knockout rather than a Knockout, because the ten-count was not completed.

Famous Boxing Knockouts

Some of the most iconic moments in boxing history have been Knockouts. Muhammad Ali’s eighth-round KO of George Foreman in the 1974 Rumble in the Jungle remains one of the sport’s defining moments. Mike Tyson’s 91-second KO of Michael Spinks in 1988 is one of the most brutal single-shot finishes on record. More recently, Canelo Alvarez’s clean single-shot KO of Amir Khan in 2016 was a textbook example of a fight ending in an instant.

What Is a Technical Knockout (TKO) in Boxing?

A Technical Knockout is declared when the referee stops the fight because one fighter can no longer safely continue, even though a full ten-count has not been completed. The key distinction from a Knockout is that the losing fighter does not have to be on the canvas for a TKO to be called. In many TKOs the losing fighter is still on their feet when the referee steps in.

Ways a TKO Can Be Declared

There are several situations that can lead to a Technical Knockout being awarded:

Referee stoppage for inability to defend. If the referee sees a fighter taking repeated unanswered shots and no longer defending themselves, they will step in to end the contest.

Corner throws in the towel. The losing fighter’s corner can signal the end of the contest by throwing a towel into the ring.

Ringside doctor stoppage. The doctor at ringside has the authority to inspect a fighter and instruct the referee to stop the fight if they judge the fighter unfit to continue. Common causes are severe cuts, swelling and suspected concussion.

Three-knockdown rule. In some jurisdictions and under some sanctioning bodies including the WBA, three knockdowns in a single round automatically triggers a TKO.

Failure to answer the bell. If a fighter cannot rise from their stool at the start of a new round, the fight is stopped and recorded as a TKO for their opponent.

Famous Boxing Technical Knockouts

Manny Pacquiao’s two-round demolition of Ricky Hatton in May 2009 finished as a TKO after the referee jumped in following a devastating final left hook. Lennox Lewis’s eighth-round TKO of Mike Tyson in June 2002 is another landmark example, ending a heavyweight rivalry that had been decades in the making. Both were emphatic finishes but neither included a completed ten-count.

KO vs TKO: The Key Difference on the Record

The single most important thing to understand about the KO versus TKO distinction is that both outcomes are recorded as stoppage wins on the fighter’s official record. When you see a boxer’s record written as “35-2, 24 KOs”, that 24 combines both Knockouts and Technical Knockouts. There is no separate KO total and TKO total on an official professional record.

This is worth remembering when comparing knockout ratios between fighters. A power puncher who ends fights with single clean shots and a volume puncher who overwhelms opponents until the referee steps in can have identical knockout percentages for very different reasons.

Other Methods of Stoppage in Boxing

KO and TKO are the two most common ways a fight ends early, but a fan or a bettor should also know about the other stoppage methods that can occur.

Retirement (RTD)

A Retirement, abbreviated RTD, occurs when the fighter or their corner formally announces that they cannot continue the fight, most often between rounds due to an injury. Zach Parker’s WBO Interim World super-middleweight title fight against John Ryder in November 2022 finished as an RTD after Parker broke his right hand and could not continue after the fourth round. For betting purposes, an RTD settles the same as a TKO.

Disqualification (DQ)

A Disqualification is declared when one fighter breaks the rules so severely that the referee removes them from the bout. Common causes include repeated low blows, hitting after the bell, headbutting or refusing to obey the referee. The opponent is declared the winner by DQ and the losing fighter takes an official loss on their record.

If the Fight Goes the Distance: Decisions

If neither fighter is stopped, the fight is decided by the three judges seated at ringside. Judges score every round using the 10-Point Must Scoring System, awarding 10 points to the fighter they believe won the round and typically 9 points to the loser. For a full breakdown of how judges score rounds and how deductions work, read our guide to how boxing scoring works.

The three judges’ scorecards are then combined to produce one of three decision types.

Unanimous Decision (UD). All three judges score the fight for the same boxer. The clearest form of decision victory.

Majority Decision (MD). Two judges score the fight for the same boxer and the third judge scores it a draw. Floyd Mayweather Jr. defeated Canelo Alvarez by Majority Decision in September 2013.

Split Decision (SD). Two judges score the fight for one boxer and the third judge scores it for the other. The majority of judges have chosen a winner but not unanimously.

There is also a Technical Decision, which occurs when a fight is stopped due to an accidental injury after a specified number of rounds have been completed. The result is then decided on the scorecards up to the point of stoppage, most commonly after an accidental clash of heads causes a cut that a doctor rules cannot allow the fight to continue.

Draws and Special Outcomes

Not every fight has a clear winner. If the judges’ scorecards do not produce a majority for one boxer, the fight is declared a Draw. There are four types.

Unanimous Draw. All three judges score the fight even.

Majority Draw. Two judges score it a draw and the third scores it for one boxer, with no boxer receiving a majority.

Split Draw. One judge scores it for each boxer and the third judge scores it a draw, splitting the total evenly.

Technical Draw. The fight is stopped very early due to an accidental injury before enough rounds have been completed for a Technical Decision.

The first Tyson Fury versus Deontay Wilder fight in December 2018 finished as a Split Draw, one of the most controversial results of the modern heavyweight era. A No Contest is a separate outcome, declared when a fight is stopped and neither boxer can be awarded a win, most often after a very early accidental injury or a failed post-fight drug test.

Method of Victory Betting Explained

Method of Victory markets let you bet on how a fight will end rather than just who wins, and they often deliver better odds than the moneyline. The most popular market at BetVictor is KO/TKO, which typically settles as a winning bet if your chosen fighter wins by Knockout, Technical Knockout, Retirement or Disqualification. Points/Decision covers Unanimous, Majority and Split Decisions, while Draw is a separate market covering all draw variants. For upcoming fights and current odds, visit boxing betting at BetVictor.

More specific markets are also available on high-profile fights. Method plus Round bets combine the stoppage method with the specific round the fight ends in, delivering longer odds for bettors confident on both variables. Method Group bets narrow the stoppage to a range of rounds such as Rounds 1 to 3, useful for backing early finishes without pinning down the exact round.

For fighters with strong knockout power, backing them to win by KO/TKO can offer significantly better value than the moneyline on the outright winner. The classic example is a heavyweight favourite fighting a shorter, less mobile opponent, where the stoppage odds may run considerably longer than the win odds despite representing the most likely outcome.
