Posh travel to Highbury to face Fleetwood Town on Saturday.
Peterborough United make the long trip north to face Fleetwood Town in Sky Bet League One action on Saturday afternoon (3pm) looking to build on the comfortable 3-1 victory over Bury at the ABAX Stadium last weekend.
Fleetwood are four points behind Grant McCann's men and drew 1-1 with Sheffield United in their last league fixture.
McCann declined to name those affected, but is hopeful that one or two should be declared fit enough to start to the encounter.
"I won't lie, we have got one or two players that are suffering with a few knocks or bumps and bruises so we will see how that develops over the next few days.
"The squad is there to be used. I was pleased with the performance in the reserve game this week and I think Shaquile Coulthirst can be a good example to others that if you knuckle down and perform well in training and the reserve games you will get your chance. He deserved his chance.
"Fleetwood have done very well over the years with their rise and they have established themsleves at this level. They have quite a compact ground and we were beaten there last year on a midweek evening so we know what to expect," McCann said.
Fleetwood are set to include former Posh striker David Ball in their attack. The former Manchester City youngster has been in fine form this year and McCann knows the threat he will pose.
"We know all about 'Bally', he is a good player and is in decent form. They have a lot of good experienced players, but they also have some young talent coming through as well. Uwe Rosler has got a good style of football. I liked watching his Brentford side play," McCann added.
Jermaine Anderson, Lee Angol and Brad Inman are still sidelined for the fixture.
