Single-elimination tournament in the context of Extra time (association football)

The men's ice hockey tournament at the 1924 Winter Olympics in Chamonix, France, was the second Olympic Championship, also serving as the second World Championships. The competition was held from Monday, January 28, 1924, to Sunday, February 3, 1924. Canada, represented by the Toronto Granites, defended its championship from the 1920 Summer Olympics. The United States and Great Britain took the silver and bronze respectively, while other contenders included Czechoslovakia, France, and Sweden.

The Bergvall system used in the 1920 Olympics was discarded in favor of a two-level round-robin tournament. Qualifying teams were placed in pools for the opening round, with the top two teams in each pool advancing to the final round. The medals were awarded based on the record in the final round. This format would remain in use until the 1992 Winter Olympics, when the final round-robin was replaced with a medal-round single-elimination tournament.

The Playoffs (in United States and Canada), Play-offs, Climax (in Japan) or Finals Series (in Australia and New Zealand) of a sports league are a competition played after the regular season by the top competitors to determine the league champion or a similar accolade. Depending on the league, the playoffs may be either a single game, a series of games, or a tournament, and may use a single-elimination system or one of several other different playoff formats. Playoff, in regard to international fixtures, is to qualify or progress to the next round of a competition or tournament.

In team sports in the U.S. and Canada, the vast distances and consequent burdens on cross-country travel have led to regional divisions of teams. Generally, during the regular season, teams play more games in their division than outside it, but the league's best teams might not play against each other in the regular season. Therefore, in the postseason a playoff series is organized. Any group-winning team is eligible to participate, and as playoffs became more popular they were expanded to include second- or even lower-placed teams – the term "wild card" refers to these teams.

Snowboard cross, also known as boardercross, is a snowboard competition in which four to six competitors race down a course. Snowboard cross courses are typically quite narrow and include cambered turns, various types of jumps, berms, rollers, drops, steep and flat sections designed to challenge the riders' ability to stay in control while maintaining maximum speed. Mid-race accidents are expected among racers.

Snowboard cross courses share common traits with motorcycle motocross courses, hence the similarity between the names of each sport. Competition format is typically a time trial followed by a knock-out tournament.

Overtime (OT) or extra time (ET) is a tie-breaking method used in various sports. If the scores are equal after the regular period of play has ended, an additional period of play - the 'overtime' or 'extra time' period - is contested to determine the winner. In some sports, this extra period is played only if the game is required to have a clear winner, as in single-elimination tournaments where only one team or players can advance to the next round or win the tournament and replays are not allowed.

The rules of overtime or extra time vary between sports and even different competitions. Some may employ "sudden death", where the first player or team who scores immediately wins the game. This rule is sometimes known as golden goal. In others, play continues until a specified time has elapsed, and only then is the winner declared. If the contest remains tied after the extra session, depending on the rules, the match may immediately end as a draw, additional periods may be played, or a different tie-breaking procedure such as a penalty shootout may be used instead.

The National Football League (NFL) is a professional American football league in the United States. Composed of 32 teams, it is divided equally between the American Football Conference (AFC) and the National Football Conference (NFC). The NFL is one of the major professional sports leagues in the United States and Canada and the highest professional level of American football in the world. Each NFL season begins annually with a three-week preseason in August, followed by the 18-week regular season, which runs from early September to early January, with each team playing 17 games and having one bye week. Following the conclusion of the regular season, seven teams from each conference, including the four division winners and three wild card teams, advance to the playoffs, a single-elimination tournament, which culminates in the Super Bowl, played in early February between the winners of the AFC and NFC championship games. The NFL is headquartered in Midtown Manhattan.

The NFL was formed in 1920 as the American Professional Football Association (APFA) before renaming itself the National Football League for the 1922 season. After initially determining champions through end-of-season standings, a playoff system was implemented in 1933 that culminated with the NFL Championship Game until 1966. Following an agreement to merge the NFL with the rival American Football League (AFL), the Super Bowl was first held in 1967 to determine a champion between the best teams from the two leagues and has remained as the final game of each NFL season since the merger was completed in 1970. The NFL is the wealthiest professional sports league in the world by revenue, and the sports league with the most valuable teams. The NFL also has the highest average attendance (67,591) of any professional sports league in the world and is the most popular sports league in the United States. The Super Bowl is also among the most-watched sporting events in the world, with the individual games accounting for many of the most watched television programs in American history and occupying the top five of Nielsen's all-time most-watched U.S. television broadcasts by 2015.

The Singapore Cup is an annual knockout football competition in men's domestic Singaporean football. Established in 1998, it is the foremost prestigious cup competition in the country. It is open to clubs in the Singapore Premier League.

Since 2004, foreign teams from other countries in Southeast Asia are occasionally invited to compete in the Singapore Cup. DPMM FC of Brunei were the first foreign team to enter the competition, years before they eventually competed in the S.League. Thailand club, Chonburi was the first foreign club reaching the final in 2006 (they lost 3–2 in the final to local club Tampines Rovers). In 2009, Bangkok Glass became the second foreign team to reach the final, losing against local club Geylang United, but they beat Tampines Rovers in 2010 to become the first foreign winners of the Singapore Cup.
