With issues still to be resolved at both the top and bottom ends of the table, League One is set for a thrilling climax on Saturday evening.
All 12 matches have been moved to a 5.30pm kick-off and it promises to be a rapidly-changing picture, especially at the foot of the table.
We explain all the final day permutations in the third tier.
Luton Town have secured their promotion but much remains to be determined in League One
Both Luton Town and Barnsley enter the final round of fixtures safe in the knowledge they have already secured promotion to the Championship.
That happened on Tuesday night when their closest promotion challengers Portsmouth and Sunderland both suffered defeat.
But with Luton and Barnsley both on 91 points, the title winner has yet to be determined.
Luton's James Collins celebrates scoring in their defeat at Burton Albion last Saturday
Barnsley were promoted without kicking a ball on Tuesday night after good results elsewhere
How the top two looks entering the final afternoon of the League One season on Saturday
The Hatters, who entertain mid-table Oxford United at Kenilworth Road, hold a four-goal advantage in goal difference over the Tykes, who travel to 16th-placed Bristol Rovers.
So if both sides win, it would require a very one-sided Barnsley victory to deny Luton the title.PLAY-OFF RACE
There is also some unfinished business in the top six. Portsmouth, Sunderland and Charlton Athletic are already assured of a play-off spot.
But the final play-off position is a shoot-out between Doncaster Rovers and Peterborough United.
Doncaster, who host Coventry City on Saturday, go into the game a point ahead of Posh, who entertain Burton Albion.
Portsmouth saw their hopes of automatic promotion ended with defeat by Peterborough
Sunderland lost at Fleetwood Town and will have to settle for the play-offs rather than top two
How the play-off picture looks in League One with one remaining slot to be determined
With the Yorkshire side having a vastly superior goal difference, Peterborough are really relying on Doncaster losing.
Also, with Portsmouth on 87 points, two above Sunderland and Charlton on 85 apiece, there could be some movement in who plays who in the play-offs.
The team that finishes third will play the team in sixth, while fourth plays fifth.
Charlton Athletic have already secured their place in the League One play-offs
It's an extraordinary picture at the bottom end of League
