1.Knockout - One of the most common ways a boxing match ends is the knockout! A knockout is described when an opponent is knocked out cold past the point of the count to ten. This gives the other opponent the win and a knockout on their resume.
2. Technical Knockout - A fighter doesn't have to be on the floor to be called a knockout.The TKO (Technical Knockout) is used when a referee stops a fight due to a lack of protection of oneself in a opponent or inadequate defensiveness. So if one fighter isn't showing the referee any signs of responsiveness throughout the fight, the referee can signal to stop the fight thus giving the win to the other fighter.
3. A Draw - Although not the best endings to a boxing match for the fans, nor the fighters, a draw usually happens when the judges score the fight evenly to both fighters. This usually is the case when both fighters are equally matched and therefore a draw is the ending result.
4. Decision - A unanimous decision, or win on points, results when all judging officials score in favor of one boxer. This is usually done by three judges, or by two judges and the referee.
A split decision, or when two judges have scored in favour of one boxer and the other judge has scored in favour of the other.
A majority decision, or when two judges have scored in favor of one boxer and the other judge has scored in favor of a draw
No Decision - Although uncommon these days, a "no decision" bout
(ND) occurred when--by law or by per-arrangement of the fighters--if
both boxers were still standing at the bout's conclusion and there was
no knockout, no decision
was rendered and neither boxer was declared the winner. There were two
primary reasons for ND bouts: 1) some jurisdictions, in an attempt to
curb gambling on the outcome of fights, enacted laws prohibiting
decisions; and 2) some reigning boxing champions, in order to protect
their titles, would demand in advance that a bout be "no decision" so
that his opponent could not capture his crown by a win on points.
5. Quitting - Term used when, during a bout, a boxer decides that he has had enough and stops fighting, resulting in a technical knockout win for his opponent.
6. No Contest - "No contest" (NC) occurs when a bout is ended before its scheduled duration, but excludes a knockout or technical knockout ending. Historically, the usual reason for a no-contest was when the referee
determined that one or both boxers were not giving their best (not
trying) and decided to end the contest, shooing the boxers out of the
ring. No-contests also occurred if the police stepped in to stop the
fight, a power failure developed, or rain forced an ending. In recent
years many United States commissions have made the official result of
bouts that end due to an accidental foul or under unusual circumstances
"no contest." Many of these bouts had been previously ruled a technical draw. An NC results in neither boxer officially winning or losing.
7. Disqualification - A boxer is disqualified by the referee and loses the bout when he repeatedly or severely fouls or infringes the rules.
