If so, manager Luke Williams must decide whether or not to thrust them straight back into the heat of battle.
Sam Hughes, Ben Woods, Tom Lees, and now Harry Leonard are reported to be definite absentees from the match at Brisbane Road.
Here is my Posh starting line-up...
1. ALEX BASS

2. CARL JOHNSTON
I'm moving the captain to his more natural right-back position for this game. He's defensively sound, as is positional rival James Dornelly, but Johnston will add more aggression going forward and attack might be the best form of defence for Posh right now. Photo: David Lowndes
3. PETER KIOSO
The stand-in central defender is no Tom Lees, but he's leading by example with some whole-hearted performances. Photo: Pete Norton
4. DAVID OKAGBUE
This powerful 21 year-old central defender has not returned to the form he was showing before his injury lay-off, certainly when in possession, but his muscle is required which keeps him ahead of George Nevett and Lucca Mendonca for now. Photo: Pete Norton
