Posh take a record of one win and eight defeats against teams currently above them in the League One table into a home game v second-placed Plymouth Argyle on Saturday.
Ferguson’s selection has been complicated by the return of midfielder Oliver Norburn from injury.
Ricky-Jade Jones and Manu Fernandez are known injury absentees.
Here’s the team the PT would pick in a 4-2-3-1 formation.

2. JOE WARD
A more natural right-back in Nathan Thompson is available again, but he's not been at his most consistent this season. Ward's speed enables him to recover lost positions more easily and he is a far greater attacking threat. Photo: Joe Dent
3. NATHANAEL OGBETA
This on-loan left-back means Posh have pace and lively attacking intent on either side of the defence. Photo: Joe Dent
4. JOSH KNIGHT
The centre-back played well on his return to the starting line-up last weekend, but obviously this is a much tougher test for him. No justification in leaving him out and his natural athleticism is a bonus. Photo: Joe Dent
