The R League (Korean: R리그), also known as the Korean Professional Football Reserve League, is the league for reserve teams of professional football clubs in South Korea.
[1][2] It was not held for nine years after the inaugural season, but was relaunched in a new format in 2000.
The participating teams were split into two or three group leagues, and the highest ranking teams of each league qualified for playoffs to determine the overall champions.
[6] Plans to resume the R League were scrapped due to a lack of participating teams as a number of teams elected to participate in the K4 League instead.
[7] K League's principle of official statistics is that final club succeeds to predecessor club's history & records.
