Northampton manager Ian Sampson is waiting on two of his key attacking threats ahead of the visit of in-form Cheltenham.
Striker Leon McKenzie remains a doubt with the thigh injury which forced him to miss the win over Lincoln on Monday while midfielder Kevin Thornton is struggling with a mystery illness.
Sampson said: "We might have to make a late decision on Leon but Kevin Thornton is very doubtful.
"Kevin has been down the hospital having blood tests and he's struggling for Saturday. He went down ill on New Year`s Eve and initially we thought he just had the flu but now we're not too sure what it is."
Ryan Gilligan is back in contention after his recovery from a bout of pneumonia and fellow midfielder Abdul Osman will make his 100th appearance for the club.
Leicester striker Craig King is available for the final game of his loan spell while Newcastle defender Ben Tozer can continue after extending his deal until the end of the season. Ryan Jarvis is back at Leyton Orient after his month with the Cobblers came to an end but defender Craig Hinton could feature after returning from his loan at Luton.
