In Boxing, An RTD (abbreviated as "referee technical decision" by BoxRec) is a boxing type and term to describe when during any rest period between rounds, a boxer refuses to continue or their corner pulls them out, thereby forcing the referee to end the fight. In contrast, a TKO (Technical Knockout) Can only be declared by the referee or the ringside doctor and it has to be during a round. RTD also stands for Corner retirement or corner stoppage. The announcer after the fight will call it off as a TKO (Thus meaning an RTD will count as a type of knockout) But it will be shown as an RTD on a boxer's win/loss record.
Mike Tyson fought Kevin McBride in 2005. In the 6th round Mike's corner refused to continue the fight during the rest break. The announcer calls it off as a TKO. But on Mike's record it is an RTD.
