Coventry City will face a trip to Doncaster Rovers next season after the South Yorkshire club, joined Barnsley and Yeovil Town in being relegated.
Doncaster, Birmingham City and Millwall were all in danger of being relegated but Millwall beat AFC Bournemouth with a Martyn Woolford header and Birmingham in a dramatic game at Bolton Wanderers came from two goals down to snatch a 2-2 draw thanks to a Paul Caddis stoppage time goal after former City striker Lukas Jutkiewicz had netted for Bolton.
Doncaster were away at Championship champions Leicester City, who were awarded a penalty which David Nugent put away. That was the only goal of the game and Rovers will be back playing League One football next season.
That leaves one place to be filled on League One next season and that will be one of Fleetwood Town, Southend United, Burton Albion or York City who contest the League Two play-offs.
