Relegation is a process in which a team is demoted from one league to another. Although not seen in the four major sports, promotion and relegation is a common occurrence in soccer. The best teams in the lower league move up whereas the worst team in the higher league moves down. The process is nearly identical in League of Legends. The 9th and 10th placed team in the North American League Championship Series enter a small tournament with the first and second ranked team in the North American Challenger Series.
This past weekend the promotion tournament took place between Team Liquid, Team EnVyUs, Gold Coin United and eUnited.
