The "Knockout Stage" is a phase in various sports tournaments, including soccer, basketball, and tennis, where teams or players compete in elimination matches. In this stage, the losing participant is eliminated from the tournament, while the winner advances to the next round. This format continues until a champion is determined. Typically, the knockout stage follows a preliminary round, where participants are ranked or seeded based on their performance. The matches are often single-elimination, meaning that each team or player has only one chance to win. This creates high-stakes competition, as every match can determine the fate of the participants in the tournament.
