Cobblers boss Keith Curle provided a fitness update on Alan Sheehan and Mickel Miller ahead of Tuesday's visit of Wigan Athletic.
“Alan is back jogging but he is not back in full training just yet,” he said.
“He knows his body and we are just waiting for the time when Alan knows that he is ready to go out and compete to be the competitor he wants to be.
“He’s had a few attempts to come back now and maybe not quite been ready. He played a couple of games when we needed him when he wasn't quite right and helped us to four points and since then we have been working to get him right. We don’t want him coming back too soon and that then leading to a more prolonged absence.
“Hopefully he will be back training in the next week to ten days.
“Mickel is back field based training and is joining in selective parts of the session. The next step for him is controlled training.”
