The Cobblers will examine the fitness of Darren Carter in the final two days of training this week to establish if he will be fit enough to face Exeter City on Saturday.
Carter has missed two weeks with a hamstring strain suffered at York City but could be available for the game against the Grecians.
Ivan Toney, who was rested for the Bournemouth game with a minor head injury, is expected to come back into the squad.
Danny Alfei has missed the past two games with a knock but should be given the green light to play this weekend.
Kelvin Langmead (Achilles), Ian Morris (knee), Lewis Hornby and Evan Horwood (both tendonitis) are out.
Exeter will be without four first-team players of their own - Jacob Butterfield (groin), Tom Nicholls (ankle), Christian Ribeiro (groin) and Jamie Reid (pelvis) and their matchday squad will include some members of the youth team.
