Southend United have missed out on the League One play-offs, despite defeating Bury 1-0 at Roots Hall.
Relegation-threatened Bury avoided the drop, with Port Vale falling short on the final day.
Irish forward Stephen McLaughlin scored the only goal of the match, after 22 minutes.
Millwall's 4-3 win at Bristol Rovers, however, meant the Lions will face Scunthorpe in the play-offs, while Bradford play Fleetwood in the other semi-final.
Sheffield United and Bolton Wanderers have both been promoted to the Championship, the Blades being crowned champions.
