Port Vale winger Paul Edwards could miss the closing weeks of the season due to an ongoing ankle problem.
Edwards sat out Monday's win over Gillingham with the injury and is due to visit a specialist to assess the situation.
He could then require two months on the sidelines and Vale boss Lee Sinnott wants to make sure Edwards is fit for next season.
Sinnott told the Sentinel: "His ankle jars, so it is a case of going to the specialist. It may need a flush out so that the ankle joint is a little bit better.
"I would imagine that won't be a long thing, but we would be talking five or six weeks or, in a worst-case scenario, eight weeks.
"The main thing is that he is fit for pre-season."
