The fight is controlled by a referee who works within the ring to judge and control the conduct of the fighters, rule on their ability to fight safely, count knocked-down fighters, and rule on fouls.

Up to three judges are typically present at ringside to score the bout and assign points to the boxers, based on punches that connect, defense, knockdowns, and other, more subjective, measures.
