Macclesfield boss Gary Simpson will be without a number of players for the clash against Northampton.
Shaun Brisley, who has been out of action for a month already, has had a scan on his hip problem and will be out for up to four months if he requires surgery to cure the problem.
Izak Reid will also miss out after failing to recover from the groin injury that forced him off at half-time during the 1-1 draw with Crewe in midweek.
Richard Butcher and Paul Bolland have returned to training following lengthy spells on the sidelines with knee and groin injuries respectively.
Young striker Ricky Sappleton is also a doubt to feature in the squad despite spending three weeks in training following a knee injury. The 20-year-old also played 45 minutes for the reserves recently but complained of swelling and is unlikely to be risked.
Northampton boss Ian Sampson is keen to name an unchanged side
Sampson saw his side tire in the closing stages of the 2-1 home defeat to Chesterfield on Tuesday night after a punishing week which saw three games and the penalty shoot-out win at Liverpool.
But the manager is still hopeful of naming an unchanged XI after calling his side's display in the Spireites defeat "excellent".
He said: "Apart from Tadhg Purcell we haven't got any other injuries and ideally I'd like to pick the same side that played on Tuesday.
"The players haven't been doing a lot in training because with the games we've had in the last two weeks it's mainly about their recovery."
Defenders Dean Beckwith (thigh) and Craig Hinton (knee) could both return to training next week while Marcus Hall was back in the squad in midweek after recovering from a knee injury.
Purcell will miss the rest of the season after suffering a serious knee injury in August.
