Leicester were crowned League One champions after a 2-0 win at Southend confirmed their promotion to the Championship.
The Foxes were virtually certain to go up but completed the task in style with a comfortable win courtesy of a second-half brace from top scorer Matty Fryatt.
Fryatt opened the scoring from the penalty spot on the hour after Simon Francis had handled in the box, and headed a second 10 minutes later to make it 31 goals for the season and ensure Leicester return to football's second tier at the first time of asking.
Second-placed Peterborough maintained their bid to go up with the Foxes automatically with a 1-0 win over Stockport, Craig Mackail-Smith chipping in the winner after 25 minutes from Aaron McLean's cross.
MK Dons moved up to third with a 1-0 win at Scunthorpe courtesy of Luke Chadwick's first-half strike, leapfrogging Millwall who were humbled 4-2 at Bristol Rovers.
The game was won in the first half, the Lions finding themselves 4-1 down and reduced to 10 men after Gary Alexander was sent off. Millwall recovered some respectability by pulling back another goal after the break, while Rovers also had a sending-off, Steve Elliott seeing red in the last 10 minutes.
Leeds are now a point behind them in fifth after a 3-1 win over Tranmere, who stay sixth. Jermaine Beckford opened the scoring with his 32nd goal of the season on the quarter hour and Neil Kilkenny doubled it 10 minutes later. Sam Sodje scored an own-goal almost immediately but Luciano Beccio wrapped up the points for Leeds in the second half.
At the other end of the table, Hereford were relegated after succumbing to a 2-0 defeat at home against Colchester but second-bottom Cheltenham retain a slim chance of survival after coming from behind to win 2-1 at Crewe.
Brighton moved to within a point of safety in 22nd after an impressive 3-1 win over Oldham, while Northampton are also only a point adrift in 21st after three late goals gave them a 3-1 win at Leyton Orient.
Elsewhere, an injury-time equaliser gave Swindon a 1-1 draw at Carlisle and Huddersfield turned round a two-goal deficit to run out 3-2 winners at Walsall.
