The basic rules of the sport of boxing are that each match consists of two boxers wearing padded gloves who punch each other in a ring for a predetermined number of rounds. A boxer achieves victory by knocking out his opponent, but if this doesn't occur, a panel of judges score the match and decide a winner.
A boxing match has one referee, who enforces the rules, in the ring with the boxers. If any fouls occur, the referee has the option of warning the boxer who committed the foul, deducting points from that boxer or disqualifying the boxer. Common fouls include illegal strikes, such as head butts, and strikes to prohibited areas, such as strikes to the groin.
If a boxer knocks his opponent unconscious, he wins by knockout. If he knocks his opponent down, the opponent has until the referee counts to 10 to get back up; otherwise, it's a knockout. The referee is able to stop the fight due to one boxer taking too much damage, which is a technical knockout.
The number of rounds varies depending on the competition level and the contract for the match. Amateur matches typically have fewer rounds than professional matches. Rounds for professional matches are three minutes long, and between each round is a one-minute break where boxers are able to rest and receive advice from their coaches.
