Corner retirement: A corner retirement (RTD) or corner stoppage are terms used in boxing to describe a fight that ends when, during any rest period between rounds, a boxer refuses to continue or their corner pulls them out, thereby forcing the referee to call an end to the fight.  In contrast, a technical knockout (TKO) may only be declared by the referee or ringside doctor, at any stage of the fight including rest periods.  In either case, an RTD still counts as a type of knockout, and is displayed as a stoppage result on a boxer's win/loss record.
