Darren Ferguson and his Peterborough United side welcome fellow promotion rivals Hull City to London Road in a crucial game on Tuesday night.
Posh come into the game off the back of a shock 2-1 defeat away to relegation-threatened Burton Albion.
Meanwhile, the Tigers picked up a 2-0 win at home against Bristol Rovers to edge one step closer to an immediate return to the second tier of English football.
Coming into the fixture, both sides occupy the top two with Hull ahead by just goal difference, however Peterborough do have two games in hand on Grant McCann's side.
Despite Ferguson's side suffering a shock defeat at Burton, he isn't likely to react by making too many changes here.
The Posh boss has no injury concerns so has a fully fit squad at his disposal.
After another win on Saturday, McCann looks set to name an unchanged side.
He will be without Brandon Fleming and Max Clark, with the pair struggling with injuries.
Peterborough United (4-3-2-1):
Pym; Thompson, Beevers, Kent, Butler, Brown, Taylor, Ward, Szmodics, Dembele, Clarke-Harris.
Hull City (4-3-3):
Ingram; Coyle, Burke, Greaves, Elder, Honeyman, Docherty, Jones, Wilks, Whyte, Magennis.
