EFL League One is the third tier of professional football in England, sitting below the EFL Championship and above EFL League Two. It features 24 teams that compete for promotion to the higher league, with the top two teams earning automatic promotion, while the teams finishing in third to sixth place enter the playoffs for a chance at promotion. The league operates on a system of promotion and relegation, meaning that the bottom teams can be relegated to EFL League Two while the top teams can move up to the EFL Championship. Each season typically runs from August to May, with teams playing 46 matches.
