Boro, bottom of Sky Bet League One, were able to introduce Darius Charles as a second-half substitute in the midweek loss to Leyton Orient after he had been suffering with a leg injury and Charles looks set to be available for selection from the start.
Michael Doughty also shook off a knock to play and he will hope to force his way into the starting line-up along with new loanee Curtis Obeng.
The Swansea defender will stay with Boro until the end of the season and will hope to feature against Posh.
