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.

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 One, where six teams remain in relegation danger.
