Pompey will aim to take the race for automatic promotion to the final day by beating Peterborough this evening.
Kenny Jackett’s side know they have to win their final two matches and hope that either Barnsley or Luton drop points on Saturday.
It is so tight at the top of the League One standings, that the Blues could still finish in any position in the top five.
But tonight’s opponents are certainly not going to roll over, as they also want to keep their hopes of Championship football alive.
Posh need a maximum haul from their last couple of fixtures if they are to have any chance of overhauling Doncaster to claim a play-off spot.
But Darren Ferguson’s troops are without a win from their past three games and were beaten 3-0 at struggling Walsall a few days ago.
Steve Evans was in charge for the first half of the campaign and he was dismissed in January, despite the team sitting sixth at the time.
United certainly have plenty of attacking firepower, with Matt Godden and Ivan Toney both into double figures for league goals and Marcus Maddison topping the division’s assists table.
Both sides were unbeaten when they met at London Road back in September, but goals from Oli Hawkins and Jamal Lowe meant it was Pompey who emerged 2-1 victors.
Meanwhile, a late strike from David Wheeler saw the Blues progress in the quarter-finals of the Checkatrade Trophy in January.
Omar Bogle has returned to training sooner than expected following a knee and ankle problem and could feature, while Jack Whatmough (knee) is still sidelined.
Peterborough have doubts over George Cooper (ankle) and Ryan Tafazolli (knee), with neither expected to be available.
