Winger Enoch Andoh was included in Port Vale’s reserve side which took on Walsall on Wednesday.
The winger is currently out of contract after turning down a deal in the summer.
However, the Ghana-born player impressed last season and now appears to be fit enough to start a game for the Valiants reserve outfit.
If Vale could agree a deal with a fit-again Andoh it would undoubtedly improve their survival bid.
The Vale reserve side also included a centre-half on trial with the club.
