Cobblers caretaker boss Andy King is reluctant to sign a loan player to replace Joe Widdowson, who could be out for up to a month with a shoulder injury.
Widdowson hurt his shoulder in the first half of the 0-0 draw at Portsmouth on December 29 and had the injury strapped up on the side of the pitch.
The diagnosis from the club’s medical team is that he will be out for four weeks, which would leave Town short of defenders with their only other left-back Lee Collins currently playing in central defence to cover Mathias Doumbe’s injury.
Ben Tozer would be an option but he has played some of the best football of his Northampton career in central midfield in recent weeks.
Or the club could make another loan signing, something King does not want to do until the situation with Widdowson is clearer.
“The physio says a month because he’s protecting his job and Joe says he’ll be back on Saturday,” he said.
“Three days would be nice but I don’t know. I have the permission of the chairman to bring a left-back in but I’m not sure I want to do that because Joe is a very good player.
“It would be difficult for me to improve the team in that area. We would be getting a young kid who wouldn’t have Joe’s experience.”
