Swindon will have midfielder Paul Caddis and striker Thomas Dossevi available after international duty.
Defenders Alan Sheehan and Callum Kennedy should return from hamstring and ankle injures respectively.
Peterborough United boss Gary Johnson told BBC Radio Cambridgeshire: "Life isn't how we would love it to be, we would love to be 10 points clear, top of the league, but it doesn't often work like that.
"I've been involved with several promotions as have Peterborough as a club and there will be ups and downs along the way.
"We'll have brilliant games and bad games, good runs and poor runs, but we've got to make sure we come out of it all in the automatic promotion places."
Swindon Town boss Danny Wilson told BBC Wiltshire: "I said at the beginning of the year that no-one would run away with the league and so far that's the case.
"You've arguably got the best three strikers in the league in the same team so if you can keep those three quiet then we've got a very good chance.
"If we've had our blip and our bad run, and I hope we have, then that's great because we're still in contact [with the top sides]."
