Peterborough captain Grant McCann will return to the starting line-up when Oldham visit London Road.
McCann was a second-half substitute during last weekend's defeat at Tranmere after featuring for Northern Ireland on the Friday night but will start as Posh look to get back to winning ways.
Winger Arron Davies is set to be out for up three weeks after picking up a hamstring injury against Tranmere.
Chris Whelpdale is fit again after a thigh injury but winger Nathaniel Mendez-Laing will have a late fitness test on his knee injury.
Full-back Mark Little is beginning a six-week lay-off after injuring his knee and midfielder Lee Frecklington (knee) remains sidelined.
Defender Gabriel Zakuani is back to full fitness after his summer groin operation but is expected to be on the bench.
Oldham have been handed a boost with midfielder Ritchie Jones and defender Reuben Hazell set to be passed fit.
Jones has missed the last two matches with a hamstring strain and Hazell was sidelined after sustaining a tear in a thigh muscle against Shrewsbury in the Johnstone's Paint Trophy.
Yet both men look set to be available and Warren Feeney returns after international duty, although striker Lewis Alessandra, who tore a calf muscle three weeks ago, remains sidelined.
Ryan Brooke, who badly damaged ankle ligaments in the final pre-season friendly against Preston, is still out but is making good progress.
Goalkeeper Greg Fleming is also well ahead of schedule following the serious knee injury sustained in the pre-season friendly at Rhyl.
