A win would probably send Trophy holders Posh through to the knockout stages, but Ferguson is also trying to nurse a depleted squad through a tough run of League One matches. Unlike Stevenage, Posh have a League One match on Saturday as Rotherham United are in town.
Here’s the team the PT would pick in the usual 4-2-1-3 formation.

2. JAMES DORNELLY
Sam Curtis is away with Ireland Under 21s so Academy graduate Dornelly must play tomorrow. He's probably in better form than Curtis anyway. Photo: Joe Dent

3. JACK SPARKES
The first-choice left-back could do with a rest, but he is the only specialist in his position in the squad currently as Harley Mills is on loan at Enfield Town. Photo: DAVID LOWNDES

4. EMMANUEL FERNANDEZ
We wouldn't mind seeing Oscar Wallin in a right centre-back role, but his minutes are being managed so he needs to miss this game in order to play in the bigger game on Saturday. Fernandez is a fit lad capable of playing twice a week. Photo: David Lowndes
