The Cobblers are waiting on the fitness of defender Jordan Willis for the midweek trip to Peterborough after the former Sunderland man came off at half-time against Charlton on Saturday.
“Jordan will be touch and go for Tuesday night,” said boss Jon Brady.
“Fingers crossed he will be okay but we will make a late decision on Jordan.
“Everyone else came through the weekend okay and I’m not expecting anyone else back just yet.”
