It is possible a draw would keep Posh in the play-off places, but, given two of the last three games for Darren Ferguson’s men are against excellent top four sides in Ipswich Town and Barnsley, it’s not likely to be enough in the long run.
Ferguson will probably not tinker too much with a side that had performed well in a six-match unbeaten run before a shocking effort at local rivals Cambridge United on Saturday.
But Joe Ward’s absence has created a problem. Here’s how the PT would solve it.
5. RONNIE EDWARDS
The England age group international can expect a few high balls in his direction on Tuesday night, but he is coping better now than he was at the start of the season. Josh Knight is currently no threat to the first-choice centre-backs. Photo: Joe Dent
6. OLIVER NORBURN
The central midfielder's levels have dipped in the last two games, but Posh need someone in the side to ensure the Saturday lethargy doesn't return on Tuesday. Photo: Joe Dent
7. HECTOR KYPRIANOU
Posh must pass the ball more accurately and at a better tempo tomorrow night and Kyprianou can help with that. Edwards to Kyprianou and then to the more advanced players is the way to go, but the ball needs to travel forwards more often than sideways. Photo: Joe Dent
8. JACK TAYLOR
I'm shifting the best player in the team into a more advanced midfield role tomorrow. Posh need a positive player in this position so either Taylor or Poku, but the latter will be needed elsewhere. Taylor can take the ball with his back to goal and turn past players. He would be a goal threat with his shooting ability and when he arrives into the penalty area in support of the strikers.
