A boxing match that has not ended in a knockout, technical knockout (TKO) or disqualification (DQ), having reached the limit on the preset number of rounds has "gone the distance" and the fighter with the higher score at the end of the fight is ruled the winner.
Because of the open-ended style of boxing judging, fights may end with controversial results, in which one of the fighters may believe they have been "robbed" or unfairly denied a victory.
The March 1999 heavyweight unification bout between Evander Holyfield and Lennox Lewis at Madison Square Garden is an example of a draw where all three judges had scored the fight differently, with Eugenia Williams favoring Holyfield, Stanley Christodoulou favoring Lewis and Larry O'Connell calling the fight a draw.
There are some scoring systems used in boxing that make it impossible for a judge to award equal points for a match.
Boxing had always traditionally been a sport for males, with men performing the officiating.
