Harvey Lintott is the latest injury doubt as the Cobblers head to Carlisle United this weekend.
The defender came off in the Easter Monday win over Gillingham and is rated as 'touch and go' for the the trip to Brunton Park.
“Harvey is coming along okay but we will have to wait and see if Saturday is too soon for him,” said Brady.
“We are not quite sure yet, it’s just a waiting game.
“We might have another player back for the weekend but again it might be too early.
“We are pushed in certain areas and with five games to go there is a bit of a trade-off. Timing is everything but there are still another four games to go after Saturday and we need to be mindful of that.
"One thing we do know is that Aaron McGowan and Akin Odimayo won't play again this season."
