At least seven teams are in the race to make the Championship play-offs.
On Monday, both Leeds United and Burnley sealed their return to the Premier League, after recording important wins.
Joel Piroe scored four goals as Leeds hammered Stoke City 6-0, before Burnley edged a 2-1 win over Sheffield United in the late kick-off.
Sheffield United had come into the game Turf Moor hoping to keep their automation promotion hopes alive and deny Leeds and Burnley early promotion parties.
But the Blades now have to settle for a place in the play-offs despite amassing 86 points from 44 matches this season.
As it stands, they would face Coventry City in the play-offs, with Sunderland potentially taking on Bristol City for a place in the final.
But just six points separate sixth-placed Coventry and West Brom down in 10th, meaning a number of clubs could yet gatecrash the play-offs places.
