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.

5. GEORGE NEVETT
The teenage left-sided centre-back is only on standby for Wales Under 19s so he can play for Posh on Tuesday. It's a chance to shine and stake a claim for more League One starts. As a left footer Nevett certainly brings balance to the back four so playing out of defence for the team should be easier. Photo: Joe Dent

6. RYAN DE HAVILLAND
The midfielder will be needed on Saturday as Archie Collins is suspended so an hour or so in this game could be useful for him. He looked good in his substitute appearance at the weekend. Photo: Joe Dent

7. DONAY O'BRIEN-BRADY
O'Brien-Brady and De Havilland are likely to be paired in central midfield against Rotherham so they could do with spending some time together in this game. Photo: Joe Dent

8. JOEL RANDALL
The enigmatic one can prove his commitment to the club by turning it on in front of a small crowd. He's our number 10. Photo: Joe Dent
