Luke Jones is expected to make a decision on his football career this week with the Mansfield Town centre half likely to decide on retirement.
Jones, a superb defender and regular goalscorer from set pieces, came back to the club for a third spell in summer 2014.
But a pre-season Achilles tendon injury has seen him have operations and long periods of rehabilitation without clearing up the problem and his contract expired in the summer.
With no light at the end of the tunnel, boss Adam Murray said: “Luke is having some bad luck.
“He’s worked his socks off to get to a certain point and it’s not improving. He’s now got a decision to make and we will speaking to Luke this week to sit down and see where we go with it.
“He is not in the best position. For someone like Jonah, who is one of the good guys in football, and there’s not many of them, it is a bit of a kick in the so-and-sos.
“But he is a strong character and, whatever his decision, he will make the right one.”
