Released Carlisle United midfielder Dean Furman is on trial with one of the Blues' League Two rivals.
The South Africa international has returned to a former club in Oldham Athletic and played in their pre-season win at Stalybridge last night.
Oldham's ex-Blues manager Keith Curle is taking a look at the 33-year-old, who was let go by Carlisle after spending last season with the club.
Furman set up one of the Latics' goals in yesterday's 2-0 victory.
The midfield man, who made 20 appearances for the Cumbrians in 2020/21, was previously on Oldham's books from 2009-13 and captained the club.
Curle has said he is well aware of Furman's qualities.
The possibility of an Oldham return for the player comes at a time the Boundary Park club are operating under an EFL embargo.
They can, though, still sign free agents and loan players.
Curle, speaking to the Oldham Times, said: "We've got to be selective with our recruitment and, in my opinion, they've got to be right.
“The first people or person to know will be the trialist when I speak to them. It's about progression and how far do I think some of the players can go.”
Ex-Carlisle forward Hallam Hope is among Oldham's summer signings under Curle so far.
