Cobblers caretaker boss Jon Brady says the squad are waiting for the results of a scan to assess the fitness of Alan Sheehan.
“Alan has gone for a scan and we are awaiting the results,” he said.
“When we get those back we will assess the situation but hopefully it’s nothing too serious."
Asked about the possibility of giving young striker and academy graduate Caleb Chukwuemeka a run in the team Brady said:
“I’ve worked with Caleb in the academy and he has a lot of good qualities.
“Caleb is undoubtedly an asset going forward and he can be a threat for us but he needs to work a lot harder off the ball out of possession. He knows that needs to come more naturally to him, and we are working hard with him to improve and develop that side of his game.”
