Speaking to the Official Club website, reserve team coach Steve McCall said : "It's a blow for John, who was looking very good in the game and closing in on returning to full fitness.
"He has been moving forward with every game but this is disappointing for him. Hopefully it's nothing too serious but it's a step back for him unfortunately."
