Manager Darren Ferguson has no injury issues to contend with as Peterborough look to maintain their 100 percent start to the season.
Joe Newell is fit again after a hand injury and the midfielder is expected to feature for the development squad next week in a friendly fixture.
Ferguson's side made it six wins from six matches as they swept aside Reading in the Capital One Cup on Tuesday night. The Posh boss made four changes for the second-round tie and admits those players that came into the team have given him food for thought.
"I have a difficult decision to make," said Ferguson. "The four players that came into the starting line-up did very well against Reading, but I know in my mind what I am going to do and the players will know on Friday."
Emile Sinclair could make his Crawley debut at Peterborough - just two days after he left Posh to join the Sussex club.
Striker Sinclair on Thursday completed his switch to the Broadfield Stadium, signing a two-year contract, and is in line for a quick reunion with his old team-mates.
Midfielder Josh Simpson will also be on familiar territory having begun his career at London Road.
Boss Richie Barker has no new injury worries and could opt to hand a full debut to winger Luke Rooney, the recent signing from Swindon.
