When a competitor is knocked out by their opponent, usually by a large blow to the head or by exhaustion. This can be by accident or intentionally. This is usually a term used in "Last Man Standing" matches after a 10 count is issued to a downed competitor. In kayfabe, however, a wrestler can be announced as having been "won by knockout". This is rarely utilized in American wrestling. Matches under the round-based system used in the United Kingdom and continental Europe can be won by knockout in addition to fall(s) and/or submission(s). In Japan, Hulk Hogan won a controversial victory over Antonio Inoki in 1983 by knockout, long debated as a possible shoot by Hogan. Knockout is also a term used as a brand name for the female wrestlers of TNA.
