Jon Brady has provided a squad fitness update with the current injury crisis showing no signs of easing.
Seven players are currently sidelined with the Cobblers boss without Ben Fox, Kieron Bowie, Lee Burge, Josh Harrop, Danny Hylton, Akin Odimayo and Ryan Haynes.
“I’d say four of those players have been main starters for us this season and have made a real difference to us,” he said.
“It’s up to the players who come in to make their own mark but we are still trying to find the right formula.
“Ben could be out for a length of time. We are still waiting on the surgeon’s opinion but we will find out pretty soon.
“Lee could be close to being back in the squad for the weekend, there is no real time scale on Danny, we are going day by day, and Kieron could still be another three or four weeks.
“Ryan has had a muscle injury and has only just started to get back on the grass and Josh also has a muscle injury.
“Akin could be another four or five weeks.”
