A lucky loser is a sports competitor who loses a match in a knockout tournament or loses in qualifying, but who then enters the main draw, usually when another competitor withdraws during the tournament because of illness, injury, or other reasons. The lucky loser then re-enters the competition, normally in place of the withdrawn competitor.
